No after sale service

Universal Roofing repaired damp at my house, however in doing so they created another problem for me and refuses to rectify it. <br> I met with the site manager (Rob), the rep (Jonty Esser) and Project manager to discuss and find a solution for the problem. We decided on a solution and they made and appointment with me to start this corrective action within 2 days. the site manager then changed the appointment, but did not pitch to do the work. This is now more than a month ago. Upon following up on the issue, I was informed by Customer Care that the solution ( to extend the concrete) will not be done as it is not part of the original job card. I can still not get hold of the site manager and the project manager confirmed that he was told by the site manager shortly after our meeting, that the job will not be completed due to it not being part of the original job card. I wonder if these 3 men would accept the job done or the treatment which I received at their own homes? they keep saying the extra work is not on the original job card, but the lowering of the floor level wasn't on this job card either??!!
