I had a leek, I asked Husain & Clifford and they came and charged me £170 the leek was still there. They kept promising to come back but never did. It got so bad I had to get another plumber, Husain promised to refund the £70 that I had to pay the other plumber to fix it, and it was linked to the water heater that they had installed, it was the valve. Can I please get this refund?
