Bad service combined with dishonest work ethics is their default standard

I contacted A247 for a blocked drain. As I used them before and their service was good, I opted to use them again and to trust them. When they were finished, the plumber opened the tap to show me the trickle of water that could not fill the basin. Later, when I filled the basin, it took 2 hours to drain. The plumber (Shaun) was phoned and his response was: " He will sort it out WHEN HE IS IN THE AREA", and that was 2 days ago. I did not withhold his payment until I was in the area of my banking app - But that is precisely what the response of this company. Strange, businesses work so hard to keep their doors open - but this company will not fix a problem for which they have been paid. The cherry on the cake was when I phoned the offices, Chantell) said that the owner would give me a call. This morning, they could not be bothered to answer the phone. And when I spoke to Shaun again, he responded that the owner would never phone a client back in the event of a problem. So, they do not just provide poor service, but also make a habit of dodging calls and being dishonest with their clients. Definitely not the same service that I received in the past.
