Unauthorized debit by "MobilityCB Netcash"

I just received an unauthorised debit on my *** NETCASH, R-96.00. I do not have any contractual agreements with anyone, especially not for any amount below R100. I dee similar complaints have been logged on Hellopeter for a couple of years now so this I can conclude it is likely **********. My funds must be returned with immediate effect and I will be logging this complaint with my bank. This is unacceptable.
