Poor Customer service for delivery

So in October of 2019 i made purchases through Mr D on all 3 occasions the food was terrible, i complained and got no feedback. After resending my complaint nearly every month thereafter they eventually responded tonask me for pictures etc bearing in mind months have passed. I then get told o was credited already. Only to then confirm that the credit was forna initial failed order and i used that credit to order the meal i initially complained about. They then asked me for proof of the orders which i sent and after numerous back and forth emails I get told i can't be helped for whatever reason they gave. I find it disgusting that a multi million rand company cant help with a complaint that dates back to October. Yes its not alot of money that was spent, neither does Mr D make the meals but they are the link amd u would expect a response immediately and a resolvement. Im very upset and disgusted about the level of service. I will never use Mr D again. I will also be sending all the emails between myself and the various people at Mr D to the tabloids. As a customer service manager I did not expect that I would get this kind of service. Absolutely appalling. Im gutted and disgusted!!!!
