Tv repair

Hi I would to report Hi Sense for poor service, On the 10th of this month they took my TV for repairs as it is still under warranty, Neeran came to my house , took my tv for backlight , I asked him how long will it take for backlight to be installed he said one week. Its gone 2 weeks now without any communication , i have been callimg them and they now say they are waiting for the part from their supplier in Capetown . I spoke to Kwanda and he promise that we gonna have TV today but now he says they arw still waiting on the supplier.these people are cruel n careless about customers.
