My money is being held "hostage "

I had potential ***** on my account and subsequently my card/account was blocked. Some of the money has been returned, no explanation as to what happened BUT I cannot access my money. I am told I have to go to a branch to sort out card and I have explained to them that I am a pensioner with limited mobility, no money and no transport so I can not physically go to a branch and would need a card to be delivered to me. I had a similar issue with another bank, a solution was found and a new card was delivered to me for my new account. I need help desperately, I need access to my money
