Vodacom putting unjustified debt on people who's accounts are in good standing, claiming that they them and canceling their contracts

Very disappointed with vodacom, they are claiming that I owe them and even canceled my account, that is up to date without any missed payment.

I had a contract with vodacom for over 15 years, a week ago my number was canceled without any explanatio, just received an sms stating that my order was processed, I was surprised as to what was the SMS referring to because I had not made any requests or been in contact with vodacom.

I went to vodacom Menlyn they told that they couldn't assist me because my number was a prepaid. I explained that I have been on a contract with them for over 15 years without interruptions. They said the system shows that I have been been a bad payer, I pulled my statements from vodacom and bank proving that I was on good standing with them. They then said it might be because the system reflects that I pay cash. Which I found to be strange because I had just presented my statements proving that they debt my account every month. They went into the system and confirmed that my account was actually in good standing with them for years and said they didn't understand why my profile was changed. They asked to go to vodacom world because they couldn't assist me in Menlyn.

Went to vodacom world and I was promised that once I submit all my statements my number will be reinstated, it's been a week in and my number is still inactive. So I called again they **** and said the number was restored a week ago, when I proved to them that they were lying. They again said it was canceled because I owe them R37k. I asked for what because my account is in good standing without any missed payments. They said they were going to investigate. Until now, there's no straight response from vodacom.
