Very Bad Service! Double payment - still no refund.

I booked a trip with Mzansigo on 19 August for delivery of furniture to my sister. The driver gave her a E-Wallet number to pay the money into. She immediately made the payment. The driver then sent the payment link to me as well and I also made the payment. I'm now still struggling to get my refund. They have excuses all the time. I'll never use their service again.!! The driver actually stole the money because they don't work with cash and he asked for the money to be paid by E-Wallet.
