Renewed - wrong billing, additional broadband and add ons not working

Hi, I am posting here as I tried to raise a complaint but the system had an error. Surprise surprise. 

There seems to have been a system error that has subscribed me to an additional broadband  - solus broadband and is charging the wrong prices for services I did subscribe to. I was already subscribed to M125 and now I also have Solus broadband. I've never heard of Solus broadband and how can I be subscribed to 2 broadband services at once !!!

Before my current deal ended I agreed to a new £24 a month contract on the 19th of February for 18 months for 125MB Broadband including flex and stream with no price increase this year. 

The same day I cancelled my existing 30 day notice Sky sports and TNT sports add ons as the discount deal had ended for those as well. I was encouraged to do this and re-add myself. This allowed me to get better deals, as on the app, skysports was £18.75 and TNT £10. So I cancelled these 2 add ons. 

The day before the 30 days was nearly up after cancellation, I attempted to resubscribe to the 2 add ons. The system on the app and online gave me errors. The following day 21st March, I was successful. 

I have had several contract notice emails come through on the 21st and 23rd of March.

One has my broadband cost as £28 and not £24. The latest includes Solus broadband !!!

I have an agreed contract agreed for  £24 a month on the 19th of February for 18 months for 125MB Broadband including flex and stream with NO price increase this year. I subscribed to skysports for £18.75 per month and TNT for £10 per month on rolling 30 day contract with no price rises for 18 months. These are my contracted services. Please can my account be updated so this is the case. £52.75 in total - less due to the 10% discount for stream add ons. 

Also, sky and TNT are still not working.This needs sorting and I shouldn't be paying for the service until it is working. Please please can these issues be resolved.
