Unfair customer service at game "********"

On Tuesday 7 April 2020 I payed my account at Game store using their account number that they send via sms. After couples of our I received sms massage again stating that "the account number you received is not right sorry, due to our technician please use the new one and ignore if you already payed" Following Tuesday I went back to the store and told them my complain, I was given a email address to report my case. I did email, attached the slip and no respond. I rate game app and state what happened, they call back and explain that is non of their matter they only concern about their app, game is the one who's responsible. Till today I haven't been assisted and my money is gone
