Vodacom is still at it....

I have taken a contract for a Samsung S20 in 2020 which to my knowledge is a 24 month contract. The contract period ended in June 2022 and to date I am being charged for the handset fee. I have logged multiple requests for the refund their escape now is that it was a 36 month contract. I asked for a copy.of the quotation where I accepted the 36 months contract or even the call recording as I am aware it was 24 months. They cannot find the contract or quotation copy showing the contract length...how convenient. I have spoken to Nonhlanhla Mzimela, Lesley Deane, Tina and many more who promise to get a copy of the agreement for me but no one comes back. I will not pay any further subscriptions until this issue is resolved as I am now expected to still pay the S20 handset cost on top of the charge for my upgrade done in November this year. How does any of this make sense. It's been a horrible experience with Vodacom over the past 2 months ans someone needs to come to the party. You need more competent staff to handle your admin.
