Vodacom's fadulent contractual extensions failure to give promised voucher

After writing a review on dishonesty and contractual ***** from vodacom, they called me to try and resolve the issue. I suppose they were senior people who do not interact with customers. I explained that I entered into an online 24 month contract and was promised a R3500 gift voucher in 2023. I never received the voucher and my contract was changed to 36 months with my consent. He promised that it would be delt with. After 2 days I received a call from an agent who told me that the contract extension was a system error and it will be fixed. She even said I will receive a confirmation email stating the actual contract duration. About the voucher, she confirmed that the contract states that i should have been given a voucher and I was referred to the department that deals with vouchers to activate it. I called them for several days and they kept referring me just to make me tired and give up. I received an sms a few minutes later that the case has been resolved. That's what characterises Vodacom. They don't really care about their clients as long as they receive their monthly payments. To date, I have not received the voucher, I have not received the letter confirming the contractual agreement. I stated in my previous complaint that they refused to give me the telephonic conversation. Honestly, I have given up. They use the same tactic to frustrate you and threaten to blacklist you if you don't pay. Yet they never honour their contractual agreements. Please I urge you not to deal with vodacom. Try other network providers for your peace.
