Unsatisfactory service

I wish there was an option for attachment. I bought a pack of 4 avocadoes at food *****'s market Bedfordview eastgate. I made coffee and when I opened them they were all rotten, black inside. Not partly rotten, completely rotten. I contacted head office which responded by saying the branch will contact me. The branch did not contact me and the head office contacted me to check if the branch contacted me and I told them that the branch did not contact me. It has been almost a month now and I am yet to receive any contact from the branch. All I asked was my refund but no one is talking to me. Now I have to use petrol again to go demand my refund.
