Netflix downgrade after renewal, breach of contract

Hi

So we renewed our contract via the app last week, exact same package, same price, job done, or so we thought. The next day when we logged onto netflix we have the standard plan with ads and limited devices.

Spoke to someone on the web chat on monday who said theyd get it fixed for us. Ive checked again today and its still standard with ads. 

Started another online chat, 45 minutes later and this time Im told netflix have changed the deal with virgin so premium is no longer offered?  

Thought Id rather speak to someone about it, as its clearly written in my contract that we will continue to receive netflix premium.Just got off the phone with customer services, 45 minutes spent waiting for an advisor only to be told again that in November things changed with netflix. I told him that my contract, agreed in December, included netflix premium so I wouldnt be accepting being left on standard. Cue 45 minutes of waiting and listening to excuses and nonsense, the upshot of which is that hes raised a ticket and I should hear back from someone in 15 days.

Ive since done some research and it seems this is happening a lot, and Ive seen some people on here have had their situation sorted, so thought Id give it a try. Its the christmas holidays so I could really do with getting what we are paying for and not having to manage who is watching netflix in our house and putting up with ads for the next 2 weeks. 

I think its shameful to treat paying customers like this, Ive now spent hours trying to get this sorted and feel like im being fobbed off in the hope that Ill let it drop. Well I wont, its in my contract and Im not getting what I paid for. Can anyone hear please try and expedite this as I am not happy at all.

Thanks
