Poor work from Game head office

I have account at Game.The 5th of september 2020.I wanted to buy on my account.They told me it is declined.I couldnt believe it.So I paid for my hing cash and paid another R1500 in my account.On the 9th of september I thought let me try again to buy on my card.Still with no luck.Now Im a guy that always pay my account.They wanted to give me a new card,but I was so angry because they made me feel like a thieve.They security checked me at head office and I was waited longer than a hour to get a new card.They told me I must hold the line that took about an hour.Im Mr.JHA Smith card number ***.I want an apology from head office.I can see clearly that why is the reason that GAME are going down.I went in there in your shops and you screened me and you knew Im the card holder.You inbarresed me in front of all the customers,when Im acually a loyal customer.My cell number is ***.I need an apology or I will still bad mouth you on social media
