Caixa bank

I have had a bank account with Caixia for a couple of years ( it was transfered from Barclays), I now notice there are charges on my account
every month under card annual quota - usually between 28 and 32 euros per month!!!!!! I have NEVER paid bank charges previously, has anyone
else experienced a similar change to their account. Or is anyone in the same position - I am in UK at present so unable to visit the branch in LC for
an explanation and hopefully a REFUND. What a ripoff and will I every get my money back ( this has only happened since beginning 2017) before this everything was fine, don't know what has changed. Any help out there? Or advice on how to challenge Hola Bank.
