Yesterday the Grenville County OPP received complaints in regards to a possible scam involving credit cards. It was reported that in each instance the caller claimed to be from either MasterCard or Visa and said they could give a reduced interest rate of 6% for life. Next they ask customers to provide their credit card number in order to proceed. Complaints were received at both the Prescott and Kemptville OPP Detachments. To report this type of scam or any other, contact Phonebusters – Canadian Anti-Fraud Centre at 1-888-495-8501 or www.phonebusters.com.
