I get calls too... except its for the person that owned the number before I bought it from Etisalat. Apparently the guy that had my number before I did ran away with some money and I keep getting calls from banks and collection agencies .. lol. and when I tell them I'm not the guy they are looking for they get all suspicious but eventually understand and stop calling. Although banks can't officially delete my no. from the system.. They've asked me to send proof of purchase before they can do that! been two months now.. I get about a call every 2-3 days... just have to deal with. Etisalat as usual cannot do anything.
