Triplicate accounts created instead of 1

We apply for a contract with Vox telecom on the 4th September 2023 and since then it was just a nightmare, at this stage there is 3 accounts created in my husbands name, according to us 2 of the accounts was created *****ulently. The 1 account show overdue on there system but on the invoice it show a zero balance and they send a sms to my husbands phone that we have to pay the outstanding amount, we did contact them and send emails and queries explaining it was a mistake from there site not ours and that they should please sort it out. We also received a letter from them to confirm the cancelation. When you login to the 2 accounts both of them show a zero balance and no services so the reason for the late payment or overdue account sms's we receive will only they be able to answer and I must say every time we log in there is some kind of shocking surprise. The only thing that I know is that it's going to have a negative reflection on our creditscore. At this stage I regret applying for a contract with Vox Telecom atleast with Telkom we nether have this issues. We only apply for 1 account not 3 and have only 1 openserve line that was installed by Telkom in 2021. They don't even received a rating, so it's with a very heavy heart that I have to rate them 1.
