Bad service from steers

I was at steers in Parkview had the bad experience ever.I went there t complain about the food I got which I was not satisfied,they told me to go back and fetch the person who bought the food for me as they will be unable to help me.now the whole shop is busy talking behind my back making it a discussion with the manager while am still at the shop they couldn't refund me cause they don't see it as a problem.had t wait for hours until they decide what to do with my complain and no conclusion was made until I phone the customer care,only attitude I got from the manager and the staff as well.
