Pathetic service from African Bank

I recently settled 1 of my loans with African Bank on 19 March 2026. Now that i am requesting a settlement letter i found out that the funds were allocated to the other account. I don't know how the bank done this when the debit was raised through their IVR system on that specific loan. After 2 days of calling the collections team to resolve the funds are still not transferred to the account that it was intended for. I get advised its escalated but nothing gets done. I am also being harassed by their lawyers. The bank and their lawyers must take note that i will not be held for any additional cost, charges or interest due to this stuff up. I will be escalating this to the FSCA and my legal team for further assistance. I will never ever use your services ever again even if i am dying and need money.
