Again! UNSATISFIED AND NO COMMUNICATION

The last time Teljoy sorted my query out now , WE back to square one , nobody answers their emails or their mailboxes is full. I have been requesting for a detailed statement about 4 times now,I am relocating and need their aircon to be removed , they want to charge me R850 which is my whole installment and also I am going to East London on my own cost to collect and bring to my new address, then I also have to pay for the installation , here ... I feel I am renting this and Samsung should have to assist and Teljoy IT ,WILL COST ME MORE THAN I think I still owe on the aircon and the worth of it ... Nobody gets back to me I eventually contacted the guy who Services the aircon and he called them. Can anybody assist me , I don't know why they treat clients so , if anyone can please get back to me or anybody give me advice , and apparently the aircon guy who called them said if I have it removed myself I lose my warranty???
