Poor Service at Covid Relief Solutions Department

On 2024-08-04 I settled my covid Relief loan using the early settlement offer (30%)by Fnb Covid Relief Dept via sms. I settled loan the very same day. However according to Fnb I am still being debited for a monthly instalment in respect of settled loan. Various attempts to call the agent at fnb Relief Solutions have been fruitless. Sometimes I hold on for more than 30 minutes only to be cut off & told call centre is experiencing technical difficulties. The no I tried to call is ***. I have been trying this no for 3 weeks nobody seems to answer.However I managed to get hold of a call centre agent from that department who indicated she will escalate problem so they can reconcile account. This hàs never materialized
