Easyflow Gutters install gone wrong

Paid deposit and Easyflow team were 4 hours late arriving. Arriving after 13h00 we were told it would take a few hours. Spoke to the office a few times while waiting and the lady either killed the call or told us that we should be patient they are on their way. We did mention that the threat of rain made us keen to get the job done but that made no difference. It then starting rain and they continued trying to install but they did not complete it. Was told the office need to re-schedule and I spoke to the owner this morning and he could not get hold of crew and would come back to me, that never happened. Now I am sitting with a job half done and no-one to complete as they are not giving me any answers. Very bad experience so far and have not seen the end of it. I fear that I might have to complete the install.
