I purchased a list of suppliers names from this company, about 4 months ago ( costing $2.25) . In the first couple of months, i failed to check my statements. My last bill had two payments ($49.96US each) When i checked my other bills, i noticed that they had charged me ($49.96US) twice on each invoice. I tried to contact them (email). & NO reply. how do you stop them from taking the money out???
