Nedbank Not willing to assist loyal customer for more than 10years

Disappointed is an undrr statement.. I was retrenched in 2020 but still managed to pay my credit card every month haven't used it at all since then.. Now that im in tight spot and cant afford to pay my personal load and credit card i wanted to take my credit card and pay my personal loan finish which then i only have 1 place to pay every minth instead of two and the interest rate is lower. By doing this i pay nedbank there money back, they dont have to phone me everytime,my name stays clear. Just to find out my credit card has been put a block on Jan 2022 why i dont know, no one contacted me, they received their monthly payments. So i phone in im told i have to apply at the creditors department for the hold to be released. Explain why i want the hold released, i explained that ive started my own little business due to that a person cant get work outside. So i had to send through a company letter head stating that i have my own little business, statements to show there is money coming in... The gentleman from Nedbank came back and said application denied. Ive asked for management contact details he reads my mails but doesnt respond. In the mean while nedbank keeps phoning, im charged interest and a bad credit score. This is what you get after being a customer for more than 10years. Highly disgusted you try to pay them back but they not willing to assist and see the reason
