Cannot close Rcs money card account

In May 2019 I asked for a settlement amount to close my account. I received and paid up my account. I emailed pop and called to notify that payment has been made and I need my account closed asap. I was told that a consultant from accounts will call within 36 working days. Till this day I have not heard from anyone in accounts. I have made numerous calls to Rcs money card and everytime they say accounts department or my team leader will contact you. No one calls back, I have to make time and call and hold on for so long before someone answers.Terrible service from Rcs money card. I want my account closed today. This level of service from Rcs money card is not acceptable.
