Repairs

I have been trying to contact your contact centre for the past few day and the phone is not going through. I bought a Tv in 2019 May at Game Alberton which went off while I was watching it about 2 weeks ago. I was lucky enough to get throughout to the call center and I was told to send an email with an invoice. I unfortunately misplaced the invoice. I have tried to get the invoice from Game alberton, provided all barcodes on the TV, bank statement and TV license details but they have escalated to their IT department with is not helping. The Tv is under 4 year warranty which is ending in May.
