Horrible and disgusting service

I ordered nandos today at pass 3, pass 4 the wrong food was delivered, while checking it the driver drove off, I called them and they said they will call me back in 2 min, after 15 min of waiting I decided to take the food back myself, I get there I was told the driver just left with my food, I got home and after 30 min the driver called he's outside it was already pass 5, to my surprise the wrong food was delivered again. He took it back. I called again and I was told it will b fixed. I waited and waited and called once again pass 6 and I was told it will b sorted out. Again I waited and nothing I called at 7 and I was told the driver almost got ******, but No1 called me.. I decided to go to nandos myself, no apology nothing, I decided to take my money and leave, is this the kind of service we get get????? Will never support them again!!!!
