Vodacom

I have a contract with vodacom I paid them the 23rd September via the vodacom app and on the 26th September I was debt the same amount I phoned vodacom the 27th to find out what was going on and then phoned the 28th and while doing so I sent vodacom two bank statements proving that I paid them twice then phoned vodacom again Sunday after everyone promised to get back to me which no has this is very unprofessional of vodacom you guys are quick to complain when we as customers owe you money and yet when you as the provider owe the customer money we as your customers must run around for our money
