MTN terrible with long standing customers

I have paid my account but MTN changed the account reference from Personal to Business. Been trying since July '26 just to get someone to do the account allocation. No luck. After at least 3-4 per week since August on call at least 40min/call. E-mails with the POP attached no luck. Icasa ticket, no luck. Your line simply gets cut, and you are handed over to legal firm. This all for an account which confirmed by MTN business has been paid. The consumer getting nailed by big business nobody taking any accountability. 30 years of being a customer means nothing and best of all your credit score id impacted in addition to legal threats. Disgraceful
