I called. The plumber turned up hours late. Looked for 5 minutes and told me he'd be back the following day to do the job. He never came back though I rescheduled twice more.
I have now been charged £118 for absolutely no work. I had to give my bank details as part of the booking. Managers won't come to the phone and I was told to email for a refund even though I never had an invoice and no work was done!
Avoid at all costs!
