false advertising from mtn to datashare

Hi does anyone know how to datashare because mtn do not know how to...For the last twenty two days I tried to datashare from my mobile and mtn do not know how to assist me...hehehe. They give me the codes *136*5# and also the old codes but everytime it tells me to contact the service provider to get the services set up. I was doing that nearly everyday for the last four weeks......they can not resolve the problem and i can not data share....be carefull when mtn advertise because it is false advertising I can not share from my own phone to another card at all... After weeks of phone calls and consultations trying to set up data share mtn could not set it up for me and i had to pay for the service......I will cancel my contracts after this false and bad service...i just like to make everyone aware of this bad service of mtn
