Perodua review: perodua 1.5 myvi

Dear Customer Service Team,
The dealership : Perodua Kulai,
Reference:
I am contacting you in order to express my concerns as my complaint has not been responded to. This happened on February 27th, 2018.
To explain in more detail I buy myvi from above dealer 1 month ago. When I bought MYVI, they tell me have to wait for 2-3weeks. But after I bought it they only tell me have to wait for 4-5 weeks. After 4-5 weeks I call them and ask why still have not release my car. Please give me dateline, and this time they don't even reply or bother me when can I get my car! Perodua services is **** lousy not even bother people!.
To resolve this issue I would like you to I like to know when can I have my car please! Change staff if they like to serve customer!.
I consider this a very serious issue which has caused me an unnecessary amount of aggravation. I would like a response within 3 days with a view to resolving this issue within 7 days. If these timescales are not met, I will have no hesitation in escalating my complaint.
Please reply to my resolver email account as I would like to keep all of my communications in my personalised complaints case file.
Yours faithfully
Sing Ching Chin
