RCS card admin is useless, rude and not sympathetic at all!

My mother passed away suddenly after an operation on the 22d of February 2020. Once the funeral was arranged we started to check which accounts were still outstanding. I went to Game to start the process of closing the RCS card my mother had and was given some forms to fill in (after we checked that there was a debt policy on the account). Sent of the paperwork, RCS came back and requested me to re-do the forms and send my ID etc as well. This took some time as it was at the beginning of the lockdown. After a few weeks, I contacted them again and told them the estate had been lodged and they could deal directly with the appointed lawyers. Got an earful about that! "We don't deal with so-and-so". OK, so I eft it thinking that everything was then in process. NO further communication was received from RCS. Then suddenly I get a phone call from RCS's collection agents! ***! I had to explain and send them all the correspondence - AGAIN. Now RCS states that the claim was declined, and that I would have been notified! Now I booted this back to the collection agents and they can deal with RCS. I would advise anybody to stay far away from using or opening an RCS card account. Useless bunch of ****** it seems.
