Bad Customer Service by Game!

Hi

On the 4th of October, i took in for repair a JBL soundbar that i had bought from Dion Wired before they closed down. I had my bank statement as proof of purchase with me but i was told i needed an invoice in order for my soundbar to be booked in. The lady who was assisting me logged a request for an invoice reprint for me the following day. I have been following up on this invoice request every second day but till today there is still no invoice and my soundbar has not even been booked for repair. This is very dissapointing customer service from Game and what makes things worse is that the poor lady at the store has been following up on this as well everyday to no avail. I am now in the dark as to the progress of this matter.
