Cloned Game Store Card - RCS ***** Division

I am really disappointed with the way RCS ***** division is handling my case. I app**** for a Game store card on the 21st January 2019 and my application was approved. However on the 23rd January ********** activity occurred on my card whilst I had not yet collected my card. I followed all the processes and sent my documents to "alldisputes" as requested and I was told that within 21 working days the investigation will be concluded. The 21 working days was on the 25th February. I called the ***** division again and was told that due to high incidents over the festive season my case was not looked at as yet. I got an email address to contact should I require any assistance. I made a follow-up on the 13th March with Carlyle the person who was apparently handling my case and to date I have not yet received any communication about the investigation. I would like this matter to be resolved as soon as possible as I constantly receive messages for payment due on purchases I did not make. Please can someone assist me with this matter?
