Disgusting customer service

Your company has the worst customer service. I am having trouble with my since April 2020. Your service department was closed during the COVID lockdown and i could not make any arrangement to have my TV fixed. In june when the lockdown moved to level 3 i made arrangements to have my TV fixed. Technicians have replaced the PC board twice and tried to load new software twice and have been unsuccessful in fixing the problems that i am experiencing. I have requested a replace device or a refund and was told that it is passed the 6 months date. No consideration was even thought about as we were all under lockdown. Your service center does not reply to emails. They have escalated my complaint on the 24/08/2020 and still no one has contacted me.
