I was given the same excuse at TM Point Shah Alam today.   
They said the plan is available and gave me the flyer, but then same thing, the option to upgrade is not available in the system.
The counter girl told me today at least 3 other users before me also having the same problem, and they said could be the HQ never update or remove from the system.

They took my thumb-print and gave me the service number form and they said they'll get back to me via SMS or email once they can upgrade my account

just got back, they checked and said my account (more than 6 months) is valid for upgrade but there is no such bonanza package in the system, so they emailed the TM headquarters and will update me soon.... so now still waiting

so tak boleh upgrade from 10Mb to 30Mb 
because I am existing customer .. 

  which tm you went to?

How to screenshot old plan.

But as you can see... my start date is still the same as when i registered for unifi lite and the date is before bonanza campaign start.

if you call them, later they realize their mistake then they push back your date.

now if all remains, you might be able to end your contract earlier.

so it looks like they U-turn ady n don allow upgrade anymore.
well.. this was given by 1 of the reseller to me... i did live chat with TM and make a dispute with them
so they logged a case for me n fwd to sales rep who will contact me within 5 working days. but i guess i can jus forget about it since none of you guys are getting it as well except for those who upgraded earlier[attachmentid=9332752]

Just got the letter after I complaint thru call 100 last weekend.
So is that mean existing customer (30mb) can add 10Rm to Bonanza package 50mb (RM189)?

Yeah...Let see what TM Point going to say.....
Ask my wife go cut the old number and apply upgrade to Bonanza 50mb for just add RM10.
Hope can approve.

Just fcome out from Tm point but TAK Boleh / from Unifi lite 129 (24 month contract ) to bonanza campaign rm139 . Unless terminate old Unifi line ( denda rm500) or u r from bonanza campaign Unifi lite rm129 ( November start),. Sorry from miscommunication with staff in the morning when visit them .

This is solution for whose contract is ended 😂

Went to tm to terminate coz mine from vip5 upgraded to lite 10mbps with same monthly fee rm149, while new sub rm129. Feeling left out as I have been using vip5 since 2011 and have 3 webe lines.

They counter offer by giving me monthly payment discount rm30, free calls 600 mins and aneka pack that I can watch using STB at home or hypptv everywhere Total I need to pay rm119 for all these. Is this good enough?

I took the offer as it got no contract extension, I still can cancel anytime.

Time fibre start operating in my home area, and the maxis one prime package is very tempting..if just they lower the price abit..

I personnally asked the tm point 2-3 times as I dont want any contract extension..she said no contract.

Seems that I need to keep all the details in case they try to tipu

Received SMS from TM on my installation date tomorrow.
But they never specified the timing, so I use Live Chat to confirm on the installation and upgrade.

So will see tomorrow how it all turns up.
Have to prepare Surat Kuasa to my wife and my photocopy IC too as I won't be at home during installation.

Same case with me. But still no sms. I tried to upgrade on Monday and no in system whatsoever, just take thumbprint. First time apply for Lite on mid July (i think).

my report they simply closed it without saying anything. u still get reply lol. 

Just went to TM point (Miri), still cant do upgrade selection. But they taken thumbprint and did verification. All I can say is there is no hope to get upgraded from unifi lite (129) to bonanza (139) anymore.
They say will contact me when they are able to do the selection is their system but I have 0% hope at the time being.
