customer service

our car is standing with multi franchise nelspruit since 13 march and up till today they didn't even bother to keep us up to date to let us know what is going on or what is happening. The problem on the car is with the keys. It is now the third time that the car went in for the same problem AND it is under a year first place and secondly they just want us to pay every time..??? HOW MUST WE PAY FOR SOMETHING THAT CANT E EN WORK FOR 1 YEAR??? It is going to be know a week and 3 days that we are sitting with out a car and NOBODY have the decency to come back to us to keep us inform of the progress. They told us last week Tuesday it will take 4 weeks to get the key here but up till know so far we know the key has not been ordered yet. Our problem is that we are sitting without a car but at that place who cares? We stressed it out that e need a car they just don't care. we cant complaint about anything because there is no service to complain about. If this is the customer services we get where will it end??????
