I had the same experience at ozlee but with another sales person. Paid deposit for the car and promised to deliver within 1 week. Weeks goes by and no news. Just left it and bought another manufacturer. Apparently, the sales person left the company and didn't pass the file to his/her colleagues. After 1 1/2 month, I received a call from another sales person from ozlee whether do I want to purchase the car or not. I told them I've already gotten my new car last month!

Ozlee.... Forget about dealing with them!

My case was the most epic.
Actually Ozlee are a bad shop to buy Proton cars.
Their SOP is scam you if possible.
Sam Wong, Bryan Lee or who ever, they are hired to scam and cheat.
Put it to Proton FB are a good way, that's how I got back my rm1000.
And must use harsh words, cheating, scamming and other words must be used. And when ever Proton post something new, reply on it and tell your problem.
Make sure to involve that FB's mod and Proton HQ also. Else they won't bother to entertain you. From the day I keep posting till get back money, it takes about 2 motnhs. Good luck.

Have you tried complaining to the manager of the branch?

Same here, have been a hard time dealing with him to get a Inspira, since it is having a big discount and other dealer/branch said they have no stock but ozlee say they have, the "manager" (not SA) told me since is a hot promo, then ask me to act fast, prepare all document for him to process loan and Rm1000 booking fee (as he mention the car is "not cheap", need extra to lock down the booking). I didn't have experience of buying a new car before this, so I just taught of if he really can help me to get a car, and I should also make all the stuff to simplify his work and get the thing done faster.

After 2-3 day passed, loan all approved, then he told me to wait, he will need to submit into system and wait for car allocation since it is so 'demanding', then wait wait wait and wait for 2 weeks, then say next week, wait next week say few days more, few days more say b4 cny sure can get for me, then after cny say wait until wat wat date... in such a long time of waiting, I have no any chassis number which he can proof that a car is allocated, and I have to called him every 2-3 days, sms, whatsapp, yeah... overall 1-2 months time.

And then I tell him, I want to cancel the booking, he ask me to draft a letter pulak, ok still fine for me to write a letter, then email to him, then even paying back my booking fee also i need to chase him like hell, wait for 2 weeks then he paying me back 1st Rm500 then wait another 2-3 weeks for the final 500... all these hassle gone thru for 2-3 month and for nothing they can do and I get nothing but wasting my time and money.

is this the same ozlee at jalan puchong (near old klang road junction)?

Honestly, Perodua gives a best service by serving walk-in customer and less(or even slight) sweet&overstated promotion/rebate/free gifts for me...

That's why many Malaysian opt Perodua rather than Proton not only the reliability of their car...

Just my 2 cents... 

Proton wont do that to a dealer who able to contribute sales, somemore they are a Malaysia top dealer who ever to contribute  130 unit ++ per month
currently they have a lot so call broker /introducer /business partner to help them gain the sales volume, maybe Kenneth225 is deal with a person such like that .
themselves is not a direct worker/staff on the shop , so if anythings happen is very hard  you argue to their manager.
For those who willing to buy car , would like to recommend get the Sa name card and call their office to verify either that Sa is work at that company or just a introducer .
i believe if you buy with a proper Sa. chances to get bad service will be low then you find the unknown Sale person from mudah / carlist
