Exceptionally bad service!

<p>Hennie quoted (32747) me on 2017-6-6. I accepted the quote on the 7th but insisted that I want a written guarantee on the installation as well (we know many people who have leaking skylights!). The installation date cannot be later than the 13th as I have tenants moving in. I sent my details via sms and Hennie promised to send an invoice and schedule the installation before due date. I phoned on the 12th as I have not heard from him. He did not reply to my sms or the message I left with his wife. I phoned again later the day and he said I should rather get some-one else to do the installation as he won't guarantee the skylight against leaks which was odd as I voiced my concerns the day he quoted and was told they have installed 55 000 skylights without any complaints! 1) Please note: no guarantee for any leakage 2) Because of his unprofessional conduct, I now have run out of time to appoint an alternative contractor 3) When I sent him an sms complaining about the bad service I was threatened.</p>
