I had Plusnet ages ago when they were still an independent company and they were amazing! they were so good to the point that I referred lots of people to use them.
After a few years with other providers, I moved into a new house about a year ago and long story short, Plusnet was the only provider that could provide me with FTTC before anyone else could so I signed up without reading any reviews on them as I thought they will still be good at what they do.. I could have been more mistaken. Simply put they don't really care anymore and their customer services are so bad.

I counted the days till I could leave them. and in order not to be charged one month more than I need too, I rang them and asked if I would be charged any penalties if I am to leave 3 days before the end of the contract. They assured me they wouldnt charge me. so I signed up to a monthly contract with NowTV broadband (not wanting to get tied down with a 12-month plan because I am in the process of sorting FTTP) my move date is 1/07/2019 and my last day with them should be 03/07/2019. a few days later I received an email from Plusnet advising me that they will charge me a penalty. I raised a ticked advising them of their already agreeing to a waiver to which I received a reply advising me to refer to the email!! They have completely lost their mojo and IMHO should be avoided at all costs!
