I phoned at 13:00 to request attention to a blocked drain. The technician arrived at 15:00 and used 3 different pieces of equipment (to maximise the charge) in a failed attempt to clear the blockage. He advised me that the drain had collapsed and they could fix it for £2,500. It would be a days work. I said no and was charged £425.76 for the hour and a quarter he was with me. My son then came round and cleared the blockage in 20 minutes using rods. This company was clearly trying to get me to (overpay) for unnecessary work.
This company has conned me out of the £400+
Steer clear of them .

UPDATE......

The following day the company's customer service manager (Lucy) phoned me with profuse apologies and a full refund of the £425.76. I could not expect more as a way of making amends for the previous days unfortunate experience.
