Unloaded airtime & unregistered cellphone banking

I bought airtime on Monday and have not received it.I called Telkom and they told me to take it up with you but every time I call your line and I’m asked security questions,I’m failed because I say I’m not registered for the cellphone banking *120* number because every time I try use it,it says I’m not registered and it refers me to your customer care line or branch. Now I’m being told I have to go to the branch to have that mistake removed when I didn’t even put it there. I’m working from home and don’t have time to be going to the branch,hence I called you but no one can seem to help me with anything.I can’t leave my work to go query R30 airtime and some nonsense you put there next to my name.If logic serves you right how can I pass every question except for that stupid one?Something in your system needs to be changed honestly or else I’m taking my account elsewhere cause I’ve never had anything as absurd as this.
