Misrepresentation by Lyndhurst Auto BMW

BMW promised me a discount of R20 000,00 with regards to the purchase price and same was confirmed on the Offer to Purchase. Upon me taking delivery of the vehicle , they have now retracted the said discount and are pressurising me to conclude the contract .<br> <br> I believe that this amounts to misrepresentation , dishonesty and bad service on their part .<br> <br> I have tried repeatedly to make an appointment with the Dealer Principal but he seems to be highly uncontactable, thus adding to my frustration and disappointment .
