FNB personal loans - credit collections

Please help me to get FNB to respond, please, as when I write letters it seems like there is always misunderstandings: I app**** for an overseas job and waited months on end for a Police Clearance and the documents to be Apostille by DIRCO. I did receive it and am now waiting for my work permit application to be approved, then it has to be taken by me to the VISA Centre to fly out of South Africa. Not sure why I explain, as it seems FNB never believed me when I lost my job to COVID and a policy had to cover those premiums. Nevertheless: I received a sms as follows from their GL Attorneys lease be aware that the grace period for delaying payment during the holidays has now concluded. We require your payment no later than 29/02/2024 on your PERSONAL LOANS LONG account. Failure to comply may result in legal action being taken against you. ***. GL Attorneys.
