PATHETIC SERVICE FOR UNAUTHORIZED ********** DEBIT ORDER

Last week Tuesday i found myself a victim of ***** , someone too a cellphone contract on my name through a marketing company under Vodacom based in Durban, for me to realize this was when my account was debited for that phone which i don't know anything about, i then took it up with my bank first FNB to find out how do they just let people debit my account without sending me debicheck authorization first and only send it the following day after debit order goes? to no surprise as always FNB never want to take responsibility when they are at fault instead i was just told to sort it with Vodacom as they can't even help me block the transaction on their side they've been blocked by the company so was i on my app and online banking,i then proceeded to phone Vodacom which confirmed my details as they are (id,banking details and name and surname) also confirmed the contract showed pending on their side so they don't understand how did they run the debit order also the phone that was **********LY on my name was a Iphone 11 but they can't see where it was delivered and who signed for it. i again need to phone those marketing people and cancel this contract they can't do it they gave me numbers that don't even go through 1 just rings with no answer then was told to go to vodacom branch where they couldn't assist me was told to phone Vodacom customer care again which they now gave me their ***** number which doesn't work either and was told again they can't cancel the contract, i ended up going to report the matter to the police which said just fill an affidavit for both companies so they can cancel which i've got currently and don''t even have details where to send , i am so frustrated with these 2 companies which claim greatness yet they are pathetic and fold their hands at the mercy of **********.
