Poor Service - warranty means nothing

I am extremely unhappy with the service I have received regarding my Hisense TV. My TV has been faulty for over a month, and I have been calling since December trying to get assistance. Every time I phone, I am told that someone will be sent out, but nothing happens unless I constantly follow up myself.

After waiting almost two weeks, a technician eventually came out. He did not even wait to see the fault on the TV. He simply took a picture, said it was the motherboard, and left, stating that a replacement would be needed. Since then, there has been no communication or progress at all.

I also contacted Amazon, where the TV was purchased, and was told very plainly that it is not their problem and that I need to deal directly with Hisense. This left me stuck between the supplier and the manufacturer with no real support from either side.

If I do not phone and chase this up myself, I hear absolutely nothing. There are no updates, no feedback, and no sense of urgency. For a well-known brand, this level of after-sales service is extremely disappointing and frustrating.
