Upgrading to fibre / poor communication

[#1]

Whilst in an existing Plusnet contract, I asked about upgrading to fibre to see if I would still receive my existing contract benefits. I was assured it would cost me an additional £6 a month for my contract and I took this on. Subsequently, bills have shot up as they now say I broke my old contract and took on a new 18 month one.
Advice to existing customers would be to shop around - and don't trust what Plusnet tell you online (didn't have the patience to wait 45 minutes over the phone!). Even with an added monthly bill for breaking a contract with Plusnet, every other provider available would still be considerably cheaper with a better service.
Further to this they are apparently now offering me a 6 month £10 discount - so just another 9 months to go on £54 a month!.
They never even notified me of this, just left a one line note on the account centre. Very disappointing service all round. On the plus side, I'll get good value from posting all my correspondence on social media.

Hi there,
Thanks for getting in touch. I'm sorry for the experience you've had. Having taken a look at the account, I can't see anywhere that we haven't been transparent about the costs of the fibre service, or the involved contract, but I do apologise if any of our correspondence was confusing.

I don't intend to get into a slanging match on here, but if you think you've been 'transparent' about the costs then you haven't read the whole thread. I quite clearly asked will my bill increase by £6 and remain for the same duration. The final two posts weren't notified to me and arent clear about the period they cover? This has proven to be a very expensive contract.
Regards
