Question for Caribbean Commercial Bank Ltd

I have a Mastercard Debit card Number ******** expiration date 5/27 and I want to know if this card is still valid? I have tried to use it on multiple occasions and have had no luck do using it. Please let me know if it is good and what I have to get it to work. It is only for $7.36 US. Thank You James Arcure. My email address is [email protected]
