Have received several missed call rom this number on several occation but don't know where it originate from and my service provider won't give me answers uness I open a criminal case!!

I got a call from +27000000000 and when I answered the call a waoman's voice said good bye

Hi There I also got a call from the same number did you manage to find out where it comes from ?

Three of my clients reported to me the calls as phoning and a voice which sounds like an African Male says "Goog-bye" and then hangs up. They are concerned. Any solution/answer as to who is calling and why???

I spoke to vodacom after receiving the call. They have no answers. My wife is on MTN...they also have no answer. Just be vigilant and watch your phone account that you don't end up with an outrageous bill.

There may be a possibility that "they" are using a system to retrieve your simcard details in order to duplicate your simcard.........then again it may be nothing or possibly have something to do with RICA.
