Apple IPad M3 OVERHEAT AND DISGUSTING TREATMENT FROM. I STORE PAVILION AND CLIENTS SERVICES

I bought an Apple Air IPad m3 at the I stoere in Pavillion- from first use (only procreate and YouTube) it overheats excessively. If I charge it it stops at 93-94% and says “charging halted due to overheating”. That product is not fit for purpose. Within plus minus 3 days of buying it we drove two hours back to Pavillion I store for a full refund. Which they refused to give us. They said they need to send it away - and it it faulty we can get a refund BUT they keep 20% handling fee. I have contacted I-store directly. They said they will solve it - that was two weeks ago. In the meantime I-store is of the opinion it does not overheat and if it does it’s our fault. I fall within my rights to get a full refund on the IPAD as it’s dangerous and not fit for purpose. They are not entitled to a 20% handling fee. Istore use to be good stores but this is ridiculous and they are bullying a client. That is not Apple qualitiy device.
