I had small charges (2) last month on my credit card and I didn't do anything about it b/c it was such a small amount of money, $3.00 I think. BUT I have another charge on my card this month that I did not make ! It is $2.99, still not a big amount but I do not intend to pay $3.00 each month that I did not make. I have tried to contact facebook to no avail. What can be done?
