Failed to Deliver as promised

Have entered into a deal to buy renault clio dynamic on a condition that the dealership install free smash and grab (part of negotiation process)<br> On the deliver it was not installed and the sales person promised to book a car with their outsourced smash and grab fitment centre till today it has not been done.<br> when the was matter brought forward to the sales manager and the DP (copied on my communication to the Sales Manager) the sales person told the sales manager that there was not such promised made. I went on further explaining to the sales manager of what has transpired till today I have been ignored.<br> <br> I'm dissatisfied with Renault Rustenburg service. I have already attempted to resolved this problem by taking above actions. Unfortunately, the problem remains unresolved. <br> <br> <br> <br>
