Unhappy consumer required paid-up update to be relayed from Groenewald Lubbe

Hi There I am really confused what is going on, i have received settlement offer from Groenewald and i have made a promise to pay the offer. I was given paid-up letters from GLA mentioning that i longer owe their client African Bank but it doesn't seem so because i am getting calls from African Bank saying that i owe them and there is no reflection of any payment received from GLA to them (African bank). I am very worried now that did i pay legitimate company on behalf of African Bank or what??? I want this matter sorted ASAP because Nudebt also claims i still owe African Bank.

Account with GLA are as follows: AFW207223 AFW207224

Can you please update payments with African Bank.

Regards, Unhappy Consumer
