Several decoder devices tested at contact centre with similar faults and after numerous emails for an agent to call me, NOTHING HAPPENING

I have already taken the decoder in on 2 different occasions and also in the past 2 weeks. They tested 3 different 2nd hand devices at contact centre that gave the exact same problem and only on the 5th device did this 1 work. But also with no guarantee that it will still be working after a while AND IN THIS CASE NOT EVEN 24 HOURS .

I cannot waste another half a day to go back in to the contact centre which would be the 3rd time in 2 weeks. Each visit alone costs the consumer money with travelling.

I honestly thought that the purpose of insurance should also cover the customer and allow for a new, (EXACT NOT RE-FURBISHED or 2ND HAND device, especially in a case like this where it takes more than 2 visits to the contact centre, have several devices tested with same problem and still no joy for the customer.
