Incorrect Bills in Oct and Nov

[CLHWDE]

Hi, I had an email on 20 Sep stating:  "Your Fibre 35 contract, which includes broadband and line rental, priced £23.31 per month, ends on 12 October 2024. In order to make sure you're getting the best value possible we've listed some options for you below.
As a valued customer we’ve decided to extend your current price of £23.31 per month for another 6 months which will end on 12 April 2025." 

However, Oct bill was £29.13 and I contacted the support in chat, they were going to credit the over charge in Nov.   However again, Nov bill is now £30.26, with a note attached: "Your discount has ended, which is why this month's bill may have gone up." 

So what was the email on 20 Sep about?  Has the decision "to extend the current price for another 6 months" been withdrawn?

I don't have any add-on/boost, apart from the free Caller Display - Free.  Package is Fibre 35.

So it should be still £23.31 per month 

I did not receive any update email since the 20 Sep.

@CLHWDE, you may have had Supersafe included free previously. 

That is not a core product so would expire. It's currently charged @ £6.00 monthly.

Only the core contract is renewed with these offers.

You need to check the details of your boosts etc. Any of the discounts connected with extras are likely to have expired, @CLHWDE.
