Outrageous Price Increase by Securitas Alarm System

"They did not call me back, so I called again and said I needed to cancel because I am moving urgently. They reduced the price to 3,500 TL as 1,000 TL for disassembly and 2,500 TL for assembly. I said the amount was still too high and that my cancellation request was valid. Since the products are rentals, they said they would charge 3,000 TL for disassembly anyway, so it would come to the same amount. Normally, the disassembly fee is 1,000 TL with a discount for moving, but it goes up to 3,000 TL for subscription cancellation. I said I did not want disassembly, that I would dismantle and deliver the products myself, but they did not accept this and said they would invoice me for all the products. I stated that if they agree, I will dismantle and deliver them myself, and if not, they should come and dismantle and collect them, but I will not pay the disassembly fee, and if they want, they can take the matter to court."
