awaiting feedback for a query for 2 & 1/2 Months with no Luck

<p>I had Upgraded my Vodacom Contract on my number ********** 004 from a uchoose 110 to a uchose 200 in June 2016. from the month of August i started experiencing a problem whereby my airtime of R90 just disappeared. I had contacted Vodacom Customer Care and they had given me a ref no.:1- ********** 5797 and had promised to sort out my query with-in 7 days. The same thing happened in September i lost R90 airtime and October i also lost R90 airtime and i was told by vodacom customer care agents it is because my contract details was not updated from a uchoose 110 to uchoose 200 so vodacom takes back R90 airtime thinking it to be a mistake to give me R200 airtime. I am really frustrated about this matter because i received no positive feedback. i always only get told my query is being investigated and escalated. please help me resolve this matter because i cant continue losing airtime because of Vodacoms mistake.</p> <p> </p> <p>Muhammed Ridwaan Minty</p> ********** <p> ********** 004</p>
