Poor Service

I am disgusted by the service received at the Game Store in Century City Cape Town. The staff members including the manager are very ***********. I purchased a defy fridge on the 22nd December. The fridge was delivered 6 days later. I was not satisfied with the product due to the temperature, has food was getting rotten. On the 18th of January at 13:40 I spoke to Azar from the store, he confirmed a technician will be sent to my house. A technician came through, he did not even assess the fridge and told me "this is the normal temperature" according to him. I then called again I spoke to Shaeed the store manager on the 23rd of Jan 2018 at 1:53 he confirmed I may exchange or request a refund, he never got back to me. I spoke to Kashifa on the 24th Jan at 14:19,she confirmed a technician will come through but nothing. Thereafter spoke Erron telephonically he also confirmed a technician will be sent, nothing. Thereafter I spoke to Shameer at the store on the 10th of Feb she also confirmed a techinician will be sent nothing. I'm so tired of this nonsense. I've been sent pillar to post with no progress. I want my money back, this a cash payment.
