Pathetic loyalty displayed by FNB

My mum Credit Card, ***31 4000, being send for legal process. Is FNB system between the cheque account n' credit card not linked to see the same notes made on the system? I'm flabbergasted on how loyalty of more 30 years can be easily tarnished easily by credit card department. My mum went on retirement in January 2015 and went inside Brits branch to complete Government Pension Fund forms with the Bank Representative to ensure that service pymt. and pension fund and future monthly pension salary payments will be paid into the FNB account. Furthermore, a note was made on the system to indicate agreement of settlement of all account upon finalisation of the retirement. We are surprised at your forwarding of this account to Barret & Associates Legal in April. First payment of the gratuity by cheque already deposited on Monday by mum to clear this Friday and accounts to be settled on Saturday (25/04/2015). You are most welcome to contact my mum as per records on your system to confirm that I'm acting on her behalf as she tends to get confused with all these monetary terminologies over the phone. Considering closing accounts after settlement n cancel future savings with FNB
