failed to honor our guarantee
KWS have failed to support & honor their 5 year Guarantee.Just after 3years .
We have had problem after problem with their product, We have contacted them time after time but we just get no response, The Director Gerry o Sullivan has spoken to us in a disgusting & appauling manner, It was just a shame he didnt speak to us like that before we placed our order.We spent a large amount of money with this company and we are appauled in the way we have been treated .
Looks like someone else knows o sullivan like the same way I know him. I see your very popular not, with a complaint on this site called crystal clear windows. tut tut!
We now have all are quotes and reports from all are companies, they all felt we have been let down with are so say 5 year guarantee, once again o sullivan has failed to make any attempt to contact us. trading standards are working with us over this matter. I guess zrn is in the same situation as we are. we have reported this company to the office of fair trading
Thank you for your comment ZRM, And for the votes.We have had the work inspected by many companies and they are appauled in the way O Sullivan has treated us as a family.We are still getting Quotes and will let you know the outcome. O Sullivan still has not got back to us.I have contacted the company that recommended them and they are deeply sorry.
The complaint has been investigated and resolved to the customer’s satisfaction.

With reference to trust mark, it maybe better to talk to them direct as I found out
If you have a issue with his new company you should create a new complaint on this site .
