Horrible, Dissapointing service VOLTEX

Voltex Briardene has debited my account twice. An error made by the store after asking me to swipe my card twice for one purchase, this happened 3 weeks ago, no one at voltex picks up this error my bank had to advise me of this. Its been 6 days that im waiting for my money to be returned back to me. I have waisted over R300 in airtime and no one has made this a priority to return the funds back to my account. The store manager Jitesh is the most unhelpful person. He doesn't answer his calls or returns them niether does he reply to emails. He has failed in the basics of service delivery... This is truly Dissapointing.... A very frustrated customer.
