Absolute joke of a company who are not interested in anything but making quick, easy money. I called on Tuesday explaining that we're a family with two very small children (2yrs and 4 months) with a blocked toilet & drain preventing us from using our only bathroom. The initial interaction couldn't have been better, but all went downhill very quickly from there. The Plumber attended and poured 2x bottles of acid in the toilet. He left 20 minutes later with instructions for us to call at 6pm if it was still blocked. When we called, we were told he couldn't do anything as he had no more acid and would come back at 10-11am the next day. He actually arrived at 4pm the next day, not 10am as promised, poured another bottle of acid down the toilet and walked out 5 minutes later leaving one more bottle of acid with my partner for us to use ourselves an hour later. This did not solve the issue. Day 3, a lovely guy named Junior (a drainage engineer) attended and he genuinely couldn't have done more if he tried (it's just a shame you work for a terrible company if you ever read this, Junior). But he explained that the issue was in the stack pipe which needed cutting open and emptying. He reported this back to dispatch to get the correct person, tools and equipment on site which he did not have on his van. Day 4, I chased at 3pm as I had still not heard anything, to be told that the engineer was booked 2-5pm. The engineer then called at 4:30pm saying he wouldn't be on site until 7pm! When I queried about the noise of cutting a stack pipe with our 2 small children at that time, he told me he was only expecting to plunge a toilet and wasn't given any details of the job from dispatch besides that and he didn't have the correct equipment either. About the only decent thing Plumbers 4 U did was not argue with me when I asked for a refund. That said, I am still out pocket for the 2 bottles of acid that the plumber demanded personal payment from my partner for, and refused to leave the flat until he was paid. Don't get tempted in by the competitive rates they promise, it absolutely isn't worth it.
