I am getting so many calls from this number and many related numbers, dont know who these people are and what they want.

When i pick up the call nobody speaks up. if any knows how to stop please let me know.

+239 292040, +239 280595, +239211162, +239 211160, +239 292044, +239 280595, +239 21161, +239 21162, +989379008921, +239 200366, Just imagine these numbers keeps on annoying you every hour but I dont answer and simply reject because I know these guys from Africa (Sao Tome & Principe etc.) are hoax and will get the load from your phone once you answer them. They have these telecom sting that once you answer, they will get the load of your mobile which they can use to call for other purpose. Guys they see your numbers from online social network sites such as Facebook, Multiply, Tweeters, or any advert online when you sell something. etc. So be careful to put your number next time. Its better to put your email rather than number. Some of the expats asnwer to an international calls because they are expecting calls from their loved ones located around the globe but unknowingly when you aswer to these spam calls you will be charged.... Be warned!!! I may changed my mobile number soon as the charge of my phone is always low when I ignore these calls that keeps on poppin in every hour.

Since 9 January I recieve constantly calls from these +239...numbers. Don't answer them, not knowing, where are they from, I am pretty sure, it will be expensive to pick up or call back.
Would it help to contact Etisalat?

even i got a miscall from this number today 24th january...

i just rcvd the no.and call back then my 25DHS credit was reduced to only 6DHS, I suggest for etisalat to have auto reject program to avoid us from this loss.
