Cellphone contract horrific experience

Hi, I am David Ngomane email address *** .I took out 2 cellphones contract during April 2025 at Vodacom Jubilee mall Hammanskraal .I was supposed to pay about 380 per month for both phones.But since April the deduction is high than expected payment.I went back to the store and they told me about paying once of payment for the Sim activation that's why it was more. Second month they did it again n this time the excuse was airtym advance from my other phone since we'll they turned my vodacom prepaid Sim into contract. It's an excuse after excuse. Every month I'm getting statements of high payment and worse now they tell me my account is in arrears R985.19 and I don't understand how. It's been two weeks my phones have been blocked. So on the 15th July 2025 they deducted the amount but my phones are still not working and also the money they deducted for airtime advance is not cleared. When my wife tries to call on my behalf coz I'm at work,they hang up on her or tell her that the is no authority for her to access my account but I have given the authority for them to assist her on my absence. What's the use of paying for phones yet you can't be helped? Since this contract I've been having problems and I'm not happy with the services.I also chose a date of the 15th of every month from the first day but they keep on debiting on the first week of evry month n sometimes they don't t even get money. The account will now create a bad credit score on my behalf. I'm pleading to you to help me n maybe IL get help. Now I just want to cancel their contract because no 1 has answer. The more you call, the more they don't give answers and they will tell you to go back to the store. Which I'm far from now. The 2 last consultant that I talked to today when calling the Vodacom *** were so rude and even hanged up. It's been so very bad. Now they deducted and meaning de account is no longer in arrears as they said but the phones are not working. I need explanation on the airtym advance, payment plan and invoices. The treatment is so painful. I'm not happy at all.
