Worst service and inferior products used or lack of s****

Initial service was good but after only a few times rain the roof started leaking again and this time on places that never was a problem as well. The office never answer when you call and when you finally do get hold of one of the foremen they make promises to come and sort out their mess but only show up when they want and not at the times arranged...then they only have a few products to only service the roof and not your sealing even though you told them that the sealing now have marks and that is also covered by the "warranty". My house now have marks on the sealing in all the rooms and still the roof is not sealed. Tried to speak to the owners but they to don't get back to you even when sending emails. I DON'T RECOMMEND ROOF PROOF RESTORATIONS TO ANYONE!!!
