Lost data, WORST SERVICE EVER

<p>More than a month ago i requested assistance from Vodacom to sort out data that is being lost evey single month, for the past three months. The contract is three years old, and only the last three months data is lost. In Januray there was more than 2 gig of data lost within a week. I have tried numerous times for Vodacom to assist me. I get phoned by a consulteant, and they will get back to me, but NO ONE comes back to me or is sorting out this problem. I have sent numerous emails, posted numerous times on their Facebook page, but nothing. They are *****ing my money and it is not acceptable!!!!! Please can someone assist before i lose my temper completely.</p>
