Appalling serve at game mall of africa

Game at Mall of Africamy patience is wearing thin, my playstation broke during lockdown, I then reported as soon as the restrictions were lowered at that time they told me they are not booking anything as their systems are down..It has been 2 a half months To my dismay their systems have been back for weeks now and they still havnt booked in my device, innitially they said I needed to bring the console so that they can take the barcode, as I did not have a reciept I did that and they said they will log a call They said that they will call me to bring the device and the call I got was that they cant find my device as and I had to bring my bank statements to show when the transaction took place and I duly obliged to which they called infact I went there to check how its going Its been two months, and I keep goin there to check, the other day they said they couldnt find the barcode the one I got on the system is wrong ..how though when they are the ones who sold it to me . They needed my card number as well and I gave them, now they say the dates, On the bank statements are wrong how so when it shows when the purchase was made? They then got the correct barcode and now its the same problem again I cant book in coz the date provided on the bank statements is wrong
