T O.

If I could give zero stars, I would. We booked a tasker to put up several large shelves. He was here for a very short amount of time but the shelves appeared to be fine, so we didn't mind. The next day I woke up to find one of the shelves on the floor, surrounded by chunks of plaster and paint. There were also several holes in our wall. The brackets had not been secured properly at all.
It's been a nightmare to deal with TR's "customer services". After several days of trying to get a response, they finally emailed back to offer us a discount on the cost of another mounting/installation task. There was no mention of fixing the damage caused. They clearly expected us to arrange it and pay for it ourselves. We rejected their voucher and demanded they pay for the repair costs but have been met with silence. Another shelf has since fallen down, causing yet more damage.
I have no faith in their complaints procedure so although we are out of pocket, it looks like we'll have to cut our losses and move on. It goes without saying that I will never use TR again and would strongly discourage anyone else from doing so. They are complete charlatans.
