Disappointed feel helpless absolutely shocking service mobicred

I opened a small line with Mobicred, I was paying it off. I opened a new standard bank account, the beneficiaries just get moved from my old account to a new account. I checked the account nr I’m using to pay my monthly payment to mobicred. It is correct. Yet in December I get a message saying they handing me over for not paying. This just one day before Christmas. I have phoned many times. I can’t get through. I send many emails I get no response from vnn or them. I don’t hear anything for a few months. Then suddenly someone calls and says do I agree to pay R 4000,00 off. I said no I’ve paid for at least 1.5 years ever month my debt should be paid off. Please send me a statement with all the ammount reflecting. She was going to phone back. I hear nothing. I only borrowed more or less R5000,00 for a washing machine. This month I get an account for 7500,00 this is absolutely ridiculous. I have send proof of payments several times. Get no reply. I ask for an updated statement with all my payments reflecting. Still no reply.... I send a message on helicopter already about this matter at the end of last year beginning of this year. Someone phoned and then said they can’t do anything about it. I need to phone the people they handed me over to. I phoned them they can’t help me I need to talk to mobicred. I feel absolutely powerless in this matter!!! I’m frustrated and angry because I’m not sure if this is going to affect my credit record. Were I have done everything to try and sort this out. But I’m not managing. I find their service absolutely shocking and will not advise anyone to Use this service.
