@Fantasia: It would be helpful if you post more detail of your tale.

EDIT: Rearranged my post so that I answer from top to bottom

RM199 for VIP20.. wow. How long is the contract?

How did they promise you? If it's just a verbal one, you got a tough thing comin. Also, when you got the mail regarding the special price, did you reply that mail? If you didn't, then you might have a chance against them.

Do you have any black & white on the beta user contract?
Assuming you didn't sign & agree that email offer end of June, I believe you can still discuss & resolve with them.
I suggest you to write down all the details from the very begining include date, who do you talk to, what was discussed/agreed, any relevant documents, etc.
In case TM refuse, you have to request to see their manager. In the event you exhausted all the avenue, you have to inform them then you have no other choice but to refer to MCMC.

Then compile all your documents, prepare to write down in points form stated very clearly the facts & straight to the point what you have gone through, most importantly state that you NEVER sign & agree to any extension nor charges thereafter, finally state what's your requirement:
1. go to : http://www.skmm.gov.my/index.php?c=public&...view&art_id=142
2. fill-up Form1-Notification of  Dispute
3. FAX to MCMC [try not to email]
4. Next day, call MCMC, ask for Complaint department, re-confirm they have received your fax, ask for the MCMC officer in charge, explain your case to him/her again.

Again, assuming you didn't sign & agree anything on the charges, whether TM call or you call is not really important.
I personally don't think you need to go through MCMC in this case, just explain calmly to TM, hope you call resolve quickly, good luck!

Fantasia, call 1-300-88-1222 for the UniFi call centre. 100 is the general TM call centre.

Is your Streamyx line under your name or under your parents name? Because, from what I know, the call centre will call the Streamyx owner to confirm after 30 June.
