WARRANTY *****

i bought my son a tablet July 2020, we had bought a cover and everything to protect the device, i also told him to be very careful with the unit as it is still covered under warranty. Never was it mentioned when bought that the unit does not get repaired but swapped out, as this would have concerned me immediately meaning there are no spares. we where not told about any warranty policies, but because i have years experience as a warranty administrator i am fully aware of the DOs and Donts. My son then bumps the tablet it chips, works 100% still, he then continues to use it for months until every time he uses the device it chargers for 10 minutes and it will tell you battery full, after 5 minutes of using the device, it will switch off telling battery dead. Next was the power button, it started going in and eventually you can no longer switch on the device as the power button has gone completely in, not only that when you insert a sim card into the device it wont pick up. I then had enough of the device and decided to take it back for repairs, i am due a years repair while still under warranty. I get to game stores during my lunch hour, i speak to a lady whom tells me, mam we cant book this in as they do not repair these units they get swapped out, also you have a small crack at the bottom. Fully aware of this i tell her i do not want you to fix anything besides the power button and the battery that is giving issues, she send me to computer department to get it check, they call down stairs and tell them to book it in. I get downstairs and this lady again tells me she wont book it in i must wait for the manager, after 10 minutes the manager Mr Brendan Attwell comes strolling along during working hours on his phone, proceeds to tell the person he will call back. I explain to him my situation and we then proceed into an argument regards the warranty policy which he has no clue of, i ask him where on this receipt is your terms and conditions listed, i have worked for Cash Crusaders and Frontosa retail supplies and we had our warranty Dos and Donts printed on the receipt, now because you do not repair these units it becomes my problem, i then tell him to book in the repair to establish if indeed the bump/crack is the cause of the button being stuck inside and the battery life being drained. He refuses to but still cannot give me clear answers to Games warranty policies and procedures, i will not tolerate or except this, it is Games issue if they do not repair these units, i am fully aware of my rights and i want my unit repaired or i will take this further.
