No Assistance on broken items and terrible service

My TV has been broken for about 2 months now and they refuse to assist. It is sitting at their head office and they say they cannot fix it even though it was insured but I must carry on paying the instalments for the next 2 years. One of the staff members says that one of her contacts can repair it and send me a quotation yet as a business they say it cannot be repaired so they Cleary just trying to make money of me. These people are useless and take forever to give feedback. We have to constantly call them. This is not the first incident with them. Almost everything that I purchased from them is broken. The quality of their products are terrible.
