Bad workmanship / bad custom service

bad installation and make promises to come rectify but never do. Today I was verbally abused by Director Peter Makgoba. Blaming me for what is wrong. I have all the mails from days after instalation and phots asking them to come sort out. More than 20 mails later - nothing . Www.seamlessgutters.co.za - they also call themselves gutterseamless.
