Disappointing Treatment

I have just had the MOST DISGUSTING SERVICE FROM FREDD FIBRE. My internet was up and running yesterday and today it was down. I called FREDD Fibre to ask what was wrong. They told me that I didn't sign a form so they blocked me. I asked what form I was supposed to sign. I was told the one emailed to me. After many attempts of telling them that I didn't receive an email and they arguing that I had as if from their office they could see into my emails, I asked to email address did they send it to and it turned out that a letter of my address was missing....they refused to admit to their mistake but all of a sudden I received the email and I was still bul**** and told that they will unblock my WiFi for 10 mins to sign the form as I needed WiFi to download the form and if the form is not returned signed it will be blocked again. I find it so strange that they apparently sent the email twice...i never received one of the two....they read out my email address incorrectly....I blew a gasket and all of a sudden the email appeared in my inbox because it was sent to the correct address. I am appalled at the treatment of their customers. They question my integrity when they sent it to an incorrect address....and I'm an existing customer. It was a second WiFi connection I took with them
