Appalling Service

I'm appalled by the service at Dion-Wired Mall of Africa: I took in my JBL speaker on Thursday 28th of March 2019, I did not have the invoice however I had my bank statement as proof of purchase. I spoke to Freddie who advised that he will request the invoice from the head-office and book the speaker in for repairs. He advised that if he can get the invoice and get the speaker booked in on the same day, I could get it the next day (Friday the 29th). I called him on Friday and he told me he was only expecting the on Monday, latest (Tuesday the 2nd of April). I just called the store again today and spoke to a lady by the name of Pretty who advised that she 'saw my speaker in some cupboard but didn't know what the story was about the speaker' and that she had no way of knowing since Freddie has not been around for days ... she was very nonchalant about the whole issue. She then went on to tell me the Head Office has a backlog in terms of getting invoices, it can take a week to get the invoice and another 21 days to fix my speaker. Please get someone, who is willing to assist, to contact me and advise 'what the story is' regarding the fixing of my speaker.
