Horrible horrible service

I received the most shocking service from Game.

I paid my account in full in April 2020. Received a message to say the amount was received. The following month I received a sms to say that I owe x amount. I ignored this as my account was paid. The following month I received another amount via sms. I phoned them and they stated that this was for insurance and explained to me that I need to actually phone them to close my account. I accepted this and advised them that I was not able to settle it immediately, as it was in the middle of the month, but I would like to make a payment arrangement to pay it on my pay date. They could not make this arrangement for me. I even went into a store to make a payment arrangement, but no success. I continued to make payments as I could. On 12 September they advised me that my account have been handed over. I immediately contacted the law firm to advise that I tried to make an arrangement with game, but they wouldn't assist me, but I will settle the amount on 25 September.

On 17 September I managed to get the money. I phoned Game to confirm the settlement amount. They could not give it to me and advised I need to phone the lawyers as my account has been handed over. I immediately phoned the lawyers. They gave me the amount. On the phone, I asked them 4-5 times: "If I pay this amount now, does that mean my account is closed and settled" - each time this was confirmed. I then settled my account.

Today, 14 October, I received another sms, stating that I owe an amount. Are you kidding?

I phoned Game. I was transferred from one person to the next. Each person shifting the responsibility to the next. They told me that I had to get a settlement letter from the lawyer and emailed them and then I should have requested to close my account. How should I know this??? They told me that lawyers can not give me a settlement amount. How should I know this??? Why the hell would I question what the lawyers tell me? Now, because there was no note made on the system, they can not reverse this. How is it my fault that someone never did their job to make a note on the system??

Who is going to own up this and take responsibility for this? I want my account CLOSED!
