Terrible service

I am not happy with Jet store at seshego circle center. I waited for over 15 minutes to be assisted,eventually I was called since I was the only person on the queue,did the transaction but i didn't not receive a receipt however the money went out,they said something about offline. Left the store and came back after 20 minutes, and I was to told to redo the purchase, and I was told that the money that went out the first time it will be refunded back after 24 hours,its been 96 hours waiting for the refund. They took my numbers and promised to call me back,nothing has been done.
