My son narrowly escapes death.

I found out in a very bad tsituation that my card has been closed. my son was heavily sick last night, i took him to a doctor in the middle of the night, I had no cash, and the card declined. I was fortunate to have gone to a doctor who showed humanity and attended my son free. Since morning, they kepts on closing my chats when i try contacting them. they dont reply on facebook. I'm stuck with a sick child and with no funds available for medical attention. Clinics in my area close at night i dont know what to do.
