*****ed off my money

Disappointed with the service received from once 1 of the best companies I've worked with. I overpaid my accounts after they were settled unaware, reached out for refund, was told to send POP, because payments were done via an app that doesn't download POP, ask vodacom for help and they sent me the POP that was forwarded to finchoice, that was not enough for them then now wanted ref numbers i dont know i paid using easy pay numbers that are appearing on the POP, went back to vodacom they told me they don't know what finchoice want because they did provide POP. Now they want me to get Ramaphosa to sign an affidavit for them to refund me my mother. It's winter my kids i cold I can't even afford to buy them clothes because they sitting there with my money
