Called out the guys to unblock my sewer, appointments were available for when it best suited myself. On the day was kept informed with ETA. Serviceman arrived but unfortunately due to my drain being a shared he was unable to perform any unblocking as it wasn’t covered by my insurance. How ever he did show me and explain what I needed to buy if I wanted to DIY, and also informed me of who to call in future which I did. So so helpful and I’m great full for the professional service I received.
