Terrible Service by Manager & Owner of Ocean Baske

I placed a telephonic order and upon my eating the food, I established that the sauce was off (which made it difficult to eat the food) & the fish was very underdone. I added a lot of garlic in the prawns and mussels in order to make the food edible, but could not stomach it. I called head office in establishing my options and was informed to possibly take the food back and request a credit at a later stage which I did and agreed with Storm(manager on duty). She indicated that the food could be prepared immediately then and I declined citing a meeting and agreed to reserve the credit for a later stage. on 2015/11/04 I went to Ocean Basket to capitalize on the order and was told that it was no longer standing as it is not provisioned in their policies. Storm completely disowned our agreement and referred me back to Head office and told me that I need to do myself a favour and request approval from Head office. I tried to reason with her and she completely denied our agreement. I requested to meet with the owner and he was less interested in resolving the matter and clearly supported Storm and offered me R100 as oppose to resolving the principle. He was unphased by the complaint.
