AirG Subscription

Once a week for three weeks I have received a text message stating that my \recurring R7.00 Subscription to AirG Social Service will be billed on [date]". I initially thought that this was an error and that I would not receive this message again. I am not prepared to spend any more time on the phone waiting for an operator and would like to be removed from this service to which I did not subscribe asap with any moneys that were billed to me returned please."""
