No Delivery

Good Day<br> <br> I bought a Polo Vivo 1.6 Sedan at Renault Imperial Princess Crossing Multifranchise-Rooderpoort on 30 October 2015,all was fine and the customer service I got that day was welcoming and warm.They promised to give me Spare keys and Disk together with Number Plate as they were busy with the Bank and making arrangement.But since then I havent heard from them and I always have to call or sent emails to get advice on what is the progress or when I will get my Number Plate as it is not safe driving around with the Car without a number plate,but I wasnt getting any reply as to when I will get my things.It is almost a month now and my 1st installment also went through but atill no sign of reply or phone calls as to when I will get my Spare key and Number plate.<br> <br> All I need is to get what I was promised by end of this week,and to find out for how long does it take for one to get a Disk and number plate after purchasing a Car?Hope to get assistance regarding my query<br> <br> Thank you in advance
