*****ing my airtime

I transferred airtime to my ****le airtime sim card in an amount of R150. When I went to buy bundles I found out I only had R130.92 and I called Telkom Mobile. I was told a case will be opend and I will get feedback in about 72 hours. I normally buy the R149 data bundle which 2GB plus 1GB night surfer.<br> <br> Because I need internet to work I had to buy another R20.00 airtime so I can purchase the bundles. R20.00 airtime I don't need. Its the system fault and why must I suffer? They could load me the bundle while they investigate and solve it. Then they will credit themselves once they find the problems.<br> This made me realise that these people ***** our money. They probably claim data we didn't use as we won't notice. Unfortunately I noticed as I had just transferred the airtime.<br> <br> I want my R20.00 back, I don't want it as airtime, I want as a refund.
