CenturyLink vs VoIPstudio

I ordered service for my residence & business, for which they sent boxes but no one ever showed up to install them. TWICE! Therefore the service was never hooked up. I continued on with spectrum. This was in May of 2019 & they have not stopped billing me or harassing me, to date. They are now trying to say I, a senior citizen ordered self install for my home & business. I would have never done that, not in a million years, that's just one of their lies. I have involved the attorney generals office & centurylink keeps saying they have sent labels to return the boxes & that they will credit everything after they get the boxes. They have never sent the labels & I can prove that through photographed daily mail, in my email. While in the middle of trying to settle things through the office of the attorney general, I get a notice that centurylink has turned my account (that I NEVER had)over to a collection agency. Keeping in mind, centurylink gave me until the 24th of march 2020 to send boxes back (without the labels they claim to have sent)in order to receive the credit, but, On March 21st 2020 is when I received the credit threat. So this is their way of working things out, by lying & deceitful actions. How can someone collect on something they NEVER provided & better yet threaten an excellent credit record for something that NEVER took place?? WORST company & customer service EVER!! Almost a whole year of harassment from this company & still have gotten NO where!
