Terrible food service

Iv seen this same review a number of times. This is the 10th time iv complained to Mr D. First they always got my order wrong. However today the delivery driver took 30 min to deliver my order from the time he had collected. Now nandos is 10 min away but Mr D told me "no the driver got lost". I paid R185 for my 1 burger and chips meal and to no surprise the food was freezing cold. They offered to send my an apology free delivery voucher of R15.00. will not be using it as this seems to be the normal for receiving cold food that you pay so much for.
