Are Persimmon really as bad as the web reviews???

I have just brought a Persimmon Home in the South West (Bristol). It's been one of the worst experiences of my life and has seriously affected our first home buying experience.
Firstly, the house was handed over to us with the keys unfinished. There were holes in the floor, plaster splatted across the floor and on the skirtings, there were marks all over the walls, our newly fitted kitchen was chipped and marked, there were holes that had been filled with plaster and then not rubbed down or painted on - it was a state!
I gave them an opportunity to put all of these errors right by taking the Sales Advisor and Site Manager round the house. I highlighted all problems and said this needed to be completed by the end of the week as we were having our flooring fitted - that we were paying for ourselves! I did not want people coming into the house to finish any work after the flooring had been put down - which I thought was more than understandable. Due to my lack of faith and trust within the company, I hired a professional snagger to come and snag our house. He took the site Manager round the house and the list only grew longer, he was also complying with NHBC standards and was standing 2 metres away to notice any problems/errors.
Both myself and the snagger reiterated this needed completing by the end of the week due to the flooring being fitted the following week.
I arrived at the house on the last day to find out only half the list had been completed. I was furious, that we gave them already two chances to put this house right!! There were still holes in the floor, the skirting's were still terrible and there was still lumps of plaster on the floor, which would interfere with our flooring being fitted! We took measures into our own hands and paid prior the floor to be latexes ourselves - which they didn't fund us for. We were devastated to find our house had not been completed and our flooring was booked to go ahead.
I then sent an email complaining to the Managing Director and Sales Manager and attached photos of house the house was handed over to us. I received an automatic reply confirming I'd receive a response within 15 days - as if I hadn't been trying to sort this out for 3 weeks already!!
15 days came and I STILL didn't receive a response, to which I emailed again. I finally had a response and had a telephone conversation with the Sales Manager who thoroughly apologised on behalf of the company. She arranged for herself to come out and see us along with the Contracts Manager - which was great.
They arrived at the house and I took them round and highlighted my problems. I did inform the Sales Manager that you couldn't see most the problems now our flooring was down and our furniture was in - it was too late...my problem was I gave them numerous occasions, numerous chances and lists of things to put right and it was never completed as promised on the agreed deadline. All they could do was apologise and they offered dot paint the house again, in which I was infuriated by as I highlighted the importance of the house being completed prior to the flooring be put down numerous of times!
That is all they had to offer for the extremely poor level of service they have given us.
I do not recommend Persimmon homes properties, the paint finish on the house was extremely poor, the house wasn't cleaned before it was handed over to us and they make false promises. I can't believe the amount of money we paid and we received a totally unacceptable service.
Your much better off paying the extra and going through Taylor Wimpey, the houses are much nicer and the quality of service and painting and their specs are much better!
