Bad service

Just over 2 months ago, my home theatre system broke. Having insurance with teljoy, i phoned them and they picked it up for repairs. Unfortunatly they system was done for. Only to find this out after 1 1/2 months after they picked it up. Then i was told they will replace it wirh another system. What a joke. Again i have to wait for a supplier. Now i hav had enough. I still hav a tv and aircon unit with teljoy. I refuse to pay anything further to teljoy. I will take that money that i owe them and i am going to get another home theatre system from somwhere else.
