Poor after care and everything else

I ordered food worth R170.10, service fee included, when the food arrived the drinks had spilled and got the paper bag containing burgers and chips wet. This resulted in the paper bag breaking and my chips falling to the ground before I could take possession of my order. I immediately calle the call centre and the said I should send photos, and choose if I would like a refund, a coupon or a replacement, I chose the coupon. To my surprise the coupon was for R35...really?? R35 This is totally poor and unacceptable service from MrD...POOR SERVICE!!
