PokerStars Casino - Ignoring refund request

I joined this site last week at the recommendation of my son and used his phone. Not sure if that is what the problem was or not (joining on my sons phone)...Pokerstars are refusing to return emails.
I deposited £100 and then had my account frozen. I had an email telling me I had a duplicate account so I emailed them back to ask they refund my £100 saying that they had let me join and THEN frozen the account which was terrible.
After emailing back and forth, it was determined that Pokerstars thought I was my daughter in law. I have no idea how they thought this...my address is different, different surname...only thing I can think of is that I joined by using my sons phone.
I provided evidence of this and Pokerstars agreed that this was acceptable...that I was NOT my daughter in law.
They then asked for Photo ID. I told them I didn't have any in date photo ID...no passport...no driving licence but I sent them everything else they asked for and I also sent them my OLD passport pic, birth certificate, ID with name and address on including Government letter and then I took pictures of ME holding some of this ID.
Since then, they have refused to reply. I have told them to refund my money or let me have access to withdraw it and they are totally ignoring me....this has been going on since 16/04/2020.
I have told them I will take this matter further as they are refusing to respond and the account is still frozen.

I received this and then sent the ID...and been ignored since...

As stated...all that they asked for has been received by them yet they are refusing to unblock the account so I can have access to my own money which is illegal.

Any help would be greatly appreciated.
I am a member of various sites and have never ever had anything like this happen.
My ID has been accepted by all (even though my passport is out of date) because it's very clear that the photo on it coincides with the name on it and MY name as well as me taking photos of me holding the ID they ask for. Seems to me this site is trying to keep my money for no other reason than it can do up until 28 days when my bank have said they will step in and retrive it if it's not given back by then.
Many thanks
