I was a client for several years before I was forced to cancel my contract when they could not resolve an issue. I wanted to add unlimited calls package to my account. A simple request you might think?
They sent me a final bill with an early disconnection fee. Then sent me threatening messages for late payment. I contacted Plusnet by telephone 01.10.20. They agreed they had charged me the early disconnection fee in error. They told me I would receive a refund. I am still waiting for the refund.
