You messed my credit record with your incompetence

I made a complaint about my account which Game has ruined on Monday, 12th February 2018 - to this day this has not been resolved. I received another SMS yesterday claiming that my payment has not been received, same context when this Holiday Payment ******* resulted in. I have just called your acc dept and spoke to a Mogamed (assisted by his manager, who is of no help at all, Arshad -Ref. ********** 01574), who now says the message is sent because the scheduled date of payment is consider 'late payment' - after having this account for almost 8 years - EIGHT YEARS, being debited at the same date EVERY SINGLE MONTH FOR EIGHT YEARS - I am now told that this is considered a late payment. A date that was offered by Game when I opened my account initially. I don't know what is happening in your organisation Game, but whatever it is I'm sick and tired of it. Additionally, I ask this gentleman to offer me an update on my ITC complaint and he could not provide me with one except for telling me something I already know and that is an update was sent to ITC. He also added that the onus is on me to follow-up with ITC, what BS! You ruined my credit record and now it is my job to make sure that YOU have done your job and resolved this?! Wow. What A TRASH RETAILER you are. I am exasperated with your lack of concern, following a blunder which YOU CREATED!!
