Account closure

Account closure I've been struggling with getting correct statements with correct balances ever since RCS took over Edgars. This year I decided to close my account. I paid off my account in March 2021 and I requested for it to be closed. I was told I would have to wait 34 business days for everything to be finalized. I also requested that I be sent a letter confirming the closure of the account. I visited one of their stores at the beginning of May and I was told that the closure was still being processed. About 2 weeks later I called their contact centre and I was told that my account had been closed already. I asked for a letter of confirmation, I was told that they would send me a paid up letter, within 48 hours, which will also specify that the account has been closed. A week later after not receiving anything from them, I called them again. This time I was told my account is still in the process of being closed. I'm sick and tired of being sent from Pillar to Post. When I asked to speak to a senior I was told to leave my details and they would call me back. I refused because they have previously said that and it was not done so this time I insisted they put me through to a senior but I was just put on hold for a long time. I'm definitely taking this up. This is a *** service!
