Poor First National Bank(FNB) Services for Private Clients

I recently app**** for credit limit increase at FNB on the 06 May 2022 and got assisted by one of the Bankers on the phone, Ms Moleboge Mogoshane. The request was successful and I was then asked to sign the agreement forms that were emailed and to send back. I did as requested and also acknowledged the agreement on my FNB App. Ms Mogoshane then told me the funds will be made available within 24hrs but to date I have not received anything. I have been making follow-ups since yesterday 09 May with Ms Mogoshane and she also indicated that she's been making follow-ups with those responsible for releasing the funds but the situation remains the same. Fortunately Ms Mogoshane has been checking with me regarding the funds but nonetheless I'm still not pleased with the situation and very disappointed on the service I'm getting and wondering when am I getting the funds?
