repair con

Very upset by this and no one cares.. I called them as I lost the signal for my DSTV. they gave me a number to call which i did. all started well. he came sorted it and advised that the dish needed to be moved. I asked him how much i wud cost to move and he said R250. I called him from the ATM to confirm and he said R250. he then said the bracket was too short and he had to go get another one. I asked if this was going to change the price and he said NO. My **** is witness to this. when he had finished the job he said no it was now R750. I am so angry. The guy is a con man. He shud have advised me before he completed the task that the price was going to be more. I asked him 3x??? I assume i have no choice but to pay him but be beware... !! I tried to call Space tv- they dont care.
