Poor service

I had two accounts handed over and paid in 2024. One was handed over to SSDA and the other to MBD. I paid the R5843.00 yet the account was handed over to Nimble to. Harassing me to pay this money again. Back in 2024 after I paid these amounts I posted a complain on Hellopeter to my numbers reactivated on prepaid. The accounts were closed and numbers are active as I was told I need to pay first then I actually did pay. But not anyone at SSDA or MBD provided paid letters . Till this days no one replies to my emails even about paid up letters. The account they referring to begins with 36xx13xx2. I have proof of payment for the account with SSDA . *** assisted me in 2024. But I used a card on the MBD portal to pay the other account. Cell C please sort this out for me. It was an account for R5843.00
