Account Suspended although payment made

I am currently very unhappy with the way MTN is treating a paying customer of almost 30 years. I used to pay my monthly contract (5 lines) via EFT. I made an EFT payment for the balance of my account on the 29th of Jan 2026. MTN then also went and took a Debit Order from my account on the 2nd of Feb 2026. I had to even send through my bank statements to prove it, crazy. My account was suspended yesterday (17 Feb), although my account is up to date. I then phoned yesterday, after the 3rd person then assisted me, it was unsuspended as they could see the payments reflecting. This morning (18 Feb) my account is suspended again. I have my whole family using lines on this account and needs service as they move around, can someone please look into this and resolve the issue please, I see it as being very unprofessional.
