Rottern Service Vodacom Mall of Africa

I went to vodacom store Mall of Africa on the 30th of November 2023 to pay my DSTV account, their Machine processed the first payment and came back with an error and i made a second payment of which also did the same thing, money was taken from my account as confirmed by my bank statement which i submitted but my DSTV was not paid, i have been struggling for weeks to get my refund from both the branch and the store manager, after several calls i was told that they did not receive the money and i should clear it with my bank, the staff is rude, slow to assist and if the person in charge of the query is not at work the others are unable to assist.
