Vodacom **** to me

Vodacom hire people who lie to customers my contract was ending 1st of November I called vodacom on the 3rd of October to make cancelation on my contract I spoke to vodacom consultant who convinced me tht wat I was paying was way to much fir the product am getting n I also told him the reason I want to cancel the contract is because I was paying way to much and am not fanancially OK he thn convinced me tht he can reduce the amount am paying make a whole new contract and IL also be getting new devices and since we'll I needed those devices and the amount I was told to pay was? +- R1300 I was thn called by another person who told me they are changing the devices bcos they hv new arrivals in stock I thn asked him am I going to pay more or thn he said IL be paying +-R1500 if they give me those new arrivals I was sold bcos it's a great deal cos I was paying R1899 and I wanted to pay less so it was a great deal to get new phones? Lesser amount but to my supprice my new payment is going to be R2400 and something 🙄🙄🙄🤔I had a shock of my life... How do I get all those recoreded calls to prove tht I dd not agree to tht amount if I knew I was going to pay tht much I wouldn't hv continued with tht deal bcos the plan was to pay less thn R1899 tht I was paying before my contract was ending... My heart is bleeding fir people to deceive u just to make sales at the end of the day the customer is the one who will be suffering for the whole 36months I am not in a good financial space for me to pay R2400 like wat am I suppose to do now bcos I hv already used the phones I am really traumatized 😭😭😭😭😭😭😭😭😭😭😭😭
