Be wary of this credit card verification scam

Are scammers using new and more direct ways after an apparent drop in scam and phishing messages this month following the raids in illegal Philippine Offshore Gaming Operators (POGOs)? 

The reason I ask is I got call from this mobile number 0967 923 0091 last August 8. The man identified himself as “Brian Go,” allegedly an employee of Bank of Philippine Islands (BPI), checking about a transaction I had supposedly made at a Mac store in Bonifacio Global City, Taguig that was over P80,000.
