Bad service

The bad service I've received from Teljoy. My pioneer amp was collected last year October for repairs and to date it has not being fixed and I also made numerous phone calls following-up on the feedback and in the process I was promise that my appliance will be fixed. Last week I received a call from Katlego notifying me that my appliance won't be fixed due to spares not being found. I would like my premiums to be refunded with immediate effect and my appliance to be delivered before the end of this week. I have read the terms and conditions of the contract the is no where it says if spares are not found the appliance will be returned back not fixed. I'm very disappointed with the service I have received from teljoy and I would not encourage any one to be part of Teljoy company.
