Complaint Review: Spectrum

My elderly, disabled and deaf mother has a landline phone for the hearing impaired, She had phone and cable tv service with Brighthouse for several years with no major problems until Spectrum took over, then her bill was hiked up so she switched to Frontier for their low introductory pricing. After a week Frontier failed to provide her with an answering service or caller id and only a few tv stations, so she switched back to Spectrum. After about 12 hours of wasted time calling trying to get Frontier disconnected and Spectrum reconnected, after another week, Spectrum has failed to provide her with any phone service at all. The tech that came out left without connecting her phone because she had decided to drop cable tv so his excuse was that that change wasnt on his work order so he said he couldnt do anything at all. Not only does she not have phone service but she has to get a new number due to Frontier's policy of hoarding and keeping the number for a verbal agreement not even an official written contract as she never signed anything. So Im thinking disability lawsuit maybe? How any company that is so incompetent can manage to have so many complaints and lawsuits against it has managed to take over nationwide is beyond my comprehension.
