Have had enough?????

Vodacom is truly playing games with me. They sent me an iPhone I never ordered called them to return it ,took them weeks to come (I never unsealed nor used the phone) been calling them for nearly two months trying to get them cancel this contract under my name instead they billed me for it the debit went off today I demand my money back into my bank account. The money they took is speared for other needs .the saddest part is I’m gonna be the one liable for an unpaid debit order because of Vodacom selfishness. I called them again today only to be told they are offline they were gonna call me back. The question is when. ? I hv 4 contracts with them I always have to bare in explained data depletion as well as airtime now this!!! No it’s enough
