Bad service at both store and customer service

On the 8th of January,amount was deducted from my account of which i had already paid.ai called customer service and they told me an agent will call me back.I called the Lichtenburg branch to explain what happened and they said i must bring my bank statement for a refund on the 9th and at about 11:25, i went in store with a statement and they said it has not yet shown on their side i should come after 12 and they will fix a refund and let me know.I went back at 4 they were busy with their works and i waited for atleast 45mins in store with no update and while waiting i heard a staff member saying they are waiting for customer to pay so that they can refund me.They were talking amongst each other then i just stoop up and left.I have been calling the customer care since Friday to this day no refund was made.I regret ever buying to this store
