Dolphin Bathrooms review: Mis Sold 1

I arranged for a Dolphin designer/salesperson to come to our home and give us an estimate for re-furbising a toilet and a shower room (also containg a toilet ). The salesperson gave us a price of £13625. Upon enquiring the high price he told us that almost half the quoted price is for the labour costs. He then stressed that Dolphin only use superior quality fittings and that out 2 rooms will be upgraded. He further said that the installation will be carried out by employees of Dolphin and that the 2 person team will be supervised by a 'site manager'. He also said that if I did not accept his offer there and then, the price will go up. Few days into the installation I discovered that the work was being done by sub-contractors (who had their own sub-contractor for electric work). Also noticed that the quality of the fittings were of much inferior quality to what I already had. Some of the fittings were not the same as specified in the contract. (Was told that the under sink cabinets would be solid wood - they are not this is just one example) The installers did not follow (perhaps they were unable to read/interpret technical drawings) the agreed design. The so called 'site manager' showed up only once for about 5 minutes and that only on the second day. The installers were supposed to remove a piece of false floor, instead they also ripped out the solid concrete floor (which they were not supposed to) and upon realising their error they went on to fill the gap with wooden planks hence leaving the floor prone to leaks. The installation is not according to the agreed desin and of course the quality of fittings and the service is not of the promised quality. I have informed Dolphin that the goods and services provided are not acceptable. Basically I want my money back because I was mis sold If it was made clear at the time of sale that Dolphin will use sub contractors I would never have agreed to have the work done. Undertakings about site manger and quality were not true .
