Price increase on first day of contract

[#1]

So, I've moved over to plusnet broadband and my contract started yesterday 1st April 2022.
I took out an 18 month fixed contract at £24.99 per month first month paid upfront).
Before I even had the chance to plug my router in, I received an email saying that my monthly payments will be £29.03 and that they are billing me for the £4.04 that I now owe.
Really...?

Hi there,

It is unfortunate timing that your service has gone live just after our price increase, but we do make you aware of this when you sign up and we go into more detail here > https://www.plus.net/help/legal/cpi-plus-guide/

I wonder if that £4.04 figure - which I had - is a sign of the discount not being multiplied by the CPI increase ? If it had it would have gone up to £27.31 and not by 16%

But if the o/p contract started at 1 April then surely no CPI increase applies - so the issue could be that the contract  was set up with pre CPI discount figures that worked if the full price was £43.50 but not now its £47.54

Finally got it all sorted.
It shouldn't have been increased and has been reset to the correct amount. It will remain the same until next March.

It was an error made on the account and shouldn't have been applied. The contract amount already included the cpi increase.
