TT Connect want me to pay R3000 for their negligence, otherwise no WiFi to run my business

I sit 4 days in without WiFi. TT Connect installed their duct next to my fireplace years ago, WiFi now not working, duct burnt and their technicians and Tech Manager - Manners Madechavo is saying I must pay R3000 to fix it because “I” should’ve have told “them” not to install there. Phindile from their customer experience centre concurs.

They the specialists not you ,the installation staff should be competent enough to determine the site condition s and where and where not install their equipment. So as the customer I should’ve gone into the roof to ensure they are not installing next to a fireplace. This is daylight *******.
