Horific after sales service from HP

Worst support ever, I took my HP notebook for repairs on the 7th of April 2025, I was notified it was a warranty repair work order number: 0006074094 and a link to track the progress, after numerous calls and emails, on the 13th of May I was sent a quotation from HP: 3014458937 that the repairs will cost R4331.00, I paid this in full on the 27th May 2025. (this was a warranty claim as HP initially said), no details were given, the invoice just stated HP Part OSS - Adv exch (Fixed Service) this quote would expire 12th June 25. after countless emails, phone calls, their is still no resolution to my notebook. Case ID: 5141216382. its been over 5x months now. I have been pushed from HP Support to Ensure Services, Reddington and for the last two months with Hemmersbach and still no one can help me!!!!!
