Direct Express complaint: Card access and usage in Europe denied

My direct express card is being denied at every ATM and all services outlets while I’m in Europe and at the moment in Portugal. I have called customer service for the last consecutive four days and each time I’ve been assured that my card will be accessible for cash withdrawals and service outlet payments in two hours after my call. I spoke to four different customer service representative, including one today with a supervisor who assured me of the same resolution that i will be able to use my card in two hours. Having tried unsuccessfully and to no avail and have spent in total of 8 hours in waiting time to get my calls answered since last Monday and today , I find no other choice to respectfully seek your assistance and save me the embarrassment of not being able to access any cash and payments . all i get is a message transaction denied by provider .
