Home-Connect and Vumatel charging more but not making a change

In January I moved into a new estate from The Huntsman.

I was able to keep my account with Home-Connect but change ISP's.

The new ISP being Vumatel. What a joke, total mess.

Some days the connectivity is down entirely - this happens every other week.

Last month, a notification came through - we are no longer offering your package and you have to pay more money for the next package up. You have no choice in the matter, it's just happening. We will automatically change your line speed.

Funny thing though, I'm paying more money but my line speed is the same?

Should I notify the Oumbudsman and bring in the CPA as well?

Absolute joke between Home-Connect and Vumatel.

Seriously.
