Cancelling my Sky Contract



I was wondering if anyone has any advice for cancelling a Sky Contract.
Almost 17 months ago I joined sky after seeing a good deal
available. I only actually wanted,
Broadband, Freeview, and Netflix, but this package gave me Sky Q too and worked out cheaper than Virgin. I spoke to a salespeople and
was told fibre broadband via Sky was not available in my area, but that normal
broadband should be fine for my purposes. However it never was fit for purpose so when the price was hiked later in the year, I used the
opportunity of a price hike to release myself from the deal.
The representative on the phone call at the time said that the price hike was associated to broadband only though so I could only
leave the broadband side and they made me stay in contract for TV until the contract ended (Next month).
Yesterday I tried to cancel the TV deal that had in my eyes finally ended only to discover that I was now in contract until March 2022! It seems an in box “Add-on” of the kid’s TV in September 2020 had bound me into a new contract, I had no idea about this at all I thought I could add the kids TV and remove as I wanted to, however I had somehow unwittingly and unknown until today signed up to Sky Signature. Yes, they sent me an email to confirm this, which they say I had read, but I do not remember opening and certainly did not read it fully.
Only after looking back through emails today, I found and read said email and it is ambiguous at best - at the top it states, “Your Add-on is confirmed” and that it was £6 per month, a £2 discount and so now £4 per month was the predominant text , I clearly at the time didn't notice ay of the further small print.
I was then informed by Sky yesterday that my situation is to get even worse – as they are removing the original offers from 17 months ago original deal. I am therefore now paying for Sky TV basic package and sperate Virgin Broadband, much more than if I had a top, sports and movies TV package.
The best they offered so far is for me to sign up for another 18 month contract with new offers, for TV I don't even use or need.
Can anyone help with this, do I have any grounds at all?
it has come at a very bad time for my family after the pandemic, and I really can not afford it at all.
