Depleted airtime/disappeared airtime

<p>On the 19th of September I recharged with R100 making my airtime R121 considering that I already had R21 left. That was around 16:00. I tried to purchase data buy couldn't. I did not use much of if as I always buy airtime to convert it ro data since I use what's app. When I slept I switched off my data. To my suprise the morning of the 20th September when I want to buy data I had a message saying my airtime is depleted. I called Vodacom to ask. They told me that they will five me feedback. I called on the 23, 24 and 25 no one is assisting me. I even spoke to Robert from solutions. Who advised that my query has been escalated. Till today my R121 airtime has been missing. This is my last resort. What's worse I tried to cancel my contract previously because of this but they retained me only to rob me.</p>
