MY WORSTE PHONE CONTRACT EXPERIENCE

I regret taking a contract phone with Vodacom, last year when I first took the phone 3 days from the day I took the contract I received an sms saying I was in arrears and I had to pay about 440 ASAP to keep my credit record good, I was stressed up because my 1st installment had not even gone off , I called there contact center I was told to pay that and note my instal was going to be 550 a month for 24 months , I paid the 440rands that’s had me in arrears 3days after I’ve taken the contract and that 1st instal was 600 and some change was ****ed as hell as I was never informed about this now this year they’ve increased my installment with me knowing about it , when I again call they “client care center” they tell me Vodacom can change my installment when Vodacom FEELS like changing it, and there’s nothing I can do about that because it in the contract so this actually mean they can keep on increasing my installment when ever they feel like doing so. I WILL NEVER TAKE A CONTRACT WITH THEM EVER EVER EVER AGAIN. Spoke to they team leader on the contact center and the other girl called kaglego something like that they also don’t give out reference numbers for the calls anymore so they say
