Steers at Grosvenorcrossing

I have orderd a steers chicken combo today was at 13hoo what I have placed my order. It takes them an hour and a half to get my food delivered by the time my food arrived it was already cold. When I call to steers at Grosvenorcrossing to speak to the manager he or she cant even pick a phone up I have left messages on the voice mail but they didnt get back to me..when I called 4 times again I ended up to speak to Nokuhanya which she has told me that she don't know if the manger is there as she is only in the call centre and can just transfer me.. I tried one more time but no success...I am also wrinting this complaint to say that steers at grosvorcrossing services is bad..and if they carry on like this they will end up losing their clients.
