Rawang, 23 January 2015. Today I received an SMS saying, "call me." This SMS actually originated from Grenada (1-473). Do not return the calls.
You will get charged at a premium call rate, if you call back and the scammers would get a portion of it. You will be kept on hold, while they play music or even run erotic audio tapes in an effort to keep you hooked. The longer they manage to keep a victim on the call, the higher they make.
These calls arrive at night or early in the morning and would ring only once or twice, ensuring the call is missed. Being off guard at such odd times, many people end up calling back, only to be kept on the phone line, for several minutes.
Leave alone all +473 series calls.
