Combi boiler with no pressure and sporadic hot water

It's a long story and I will try to summarise in bullet points: -I needed to replace an old boiler and was given two quotes -I went with the combo boiler option as after reading online, it seemed the best option for the small flat -the boiler was fitted and immediately I noticed that the once wonderful shower, now had no pressure and that the hot water was sporadic -when approached, the plumbing firm said that they had removed the pump as it was not compatible with the combi boiler. This was not quoted for and was not authorised at any point. If I had known either before or during the work, I would have chosen the non-combi option which is compatible with a pump. -Four months on, I am still trying for a resolution but the one they are now giving through their guild is what I asked for originally and the co. said it was 'unsafe and would pollute the water supply'. How is it now safe? Please can you advise if this will work and why their suggesting it means it is safe, when it wasn't when I suggested it...? I only want to know that it is alright and that it will not start another set of problems. To reinstate the pump: Drain down the system Take hot water feed from the boiler to the kitchen tap Reinstate original cold to feed cylinder Run flow and return from the combination boiler to feed the cylinder to supply hot water for the shower Re-instate the original pump Supply and fit 2 x 2 port valves to operate both heating and hot water Supply and fit a new timer clock Supply and fit a new cylinder stat This has caused me so much stress and money, not to mention devaluing my home as a result of the ineffective bathroom. I am desperate for it to be resolved. Fitting an electric shower has also been suggested by others but I have a very expensive shower, which was brilliant. Also, would that be more powerful? Would it solve the problem of hot water dropping out mid shower? Thank you in advance for any help
