Pay Joy and Vodacom pathetic service

My younger sister took out a Pay Joy contract with Vodacom on the 17.06.2022 . We were advice that they are not fami**** with the Pay Joy contract and how it works , we will be the first clients they will sell it to. Being understanding and patient going through the process with them. On the day we finalized the contract we took our deposit as we were advice to pay a upfront deposit. When we got there they told us that we no longer have to pay the deposit . We only pay that amount at the end of the contract. So we left with the deposit and the phone . A week later the consultant phoned us to inform us that Pay Joy wants the deposit . Already baffled with the whole situation , we learned that we have to do a weekly payment instead of a monthly payment as we agreed. We went back to the shop to get some answers but nothing. I have to say the service we got has been absolutely trash and employees of the Vodacom Upington is very *********** . Our issues is still not resolved and we sitting with a locked phone. Can Pay Joy please provide proper training to there outsourcing companies . We as clients are being affected by this now. And what really gets me is that Vodacom is not taking accountability and it seems like we are at fault . Very disappointed in Vodacom .
