Airtime disappeared

I am on Telkom top up business contract,I loaded my phone with R100 airtime in turn bought 1gig of data for R99,money was taken out from my account for the data,then then next thing am getting the message that am using out of bundles data,money was returned to my account without me being notified.I called telkom contact centre and am being told my administrator needs to call telkom. Where am I even going to get my administrator in this situation,hes on leave,I need to use my phone whereby I bought airtime with my own money.

Telkom dont try to come with tricks of chowing our money so we could buy airtime,I want my money back as now the money left in my account cant but 1Gig anymore,where did my money go as this issue doesn't need an administrator,get your house in order and train your call centre agents better
