Not to be relyed on

We had a job done by RelyOn Enterprises where they installed built-in cupboards. Initially the job was done fairly well with a few problems, as detailed below. There however was an issue that the table tops were all at a lower level to the original. This caused a few problems - there is a visible mark on the wall tiles where the original table top was and the plumbing could not be reconnected. They never reconnected the plumbing - I needed to get a plumber to re-pipe the section under the sink. They never cleaned the walls where the original table tops where - this is around the entire kitchen. The other issue was that when they connected the cupboards around the electrical switch box they did not leave enough space for the electrician to remove the front cover - their response was that they were not able to fix this and that I must get the electrician to cut the cover - this is going to look unsightly. Due to a flooring issue from another contractor they had to remove some of their cupboards. They then re-quoted to replace the removed units. There are a few small issues that I cannot get them to come and fix or even to return my calls - although this gets promised each time.I have also been promised by the owner that these issues would be attended to - with no joy. The one is that a part of the table laminate got damaged and they said they would fix this - weeks ago - I had to find a place where they could get it from - even though they supplied it originally. From what started out as quite a professional way of operating, the customer service of RelyOn begs the question of where they got their name from.
