Migration to a new contract

I migrate to the MtnChoice top up as the consultant at the Mtn store told me I could buy data with the R200 received every month. That was ideal for me as I only use data for Internet and WhatsApp. After I got my first money I could buy data with the money. Went backwards and forwards to the Mtn store logging calls wasting hours of valuable time. The promise to put me back to my previous package but after 2 months still nothing happened. Still they paying me in R200 worthless money I don't want. I have severely ref no ***, ***, ***, ***, USD:***. I already lost more than 1 gig data with the migration process and R600. Mtn is *****ing from me with their lies and promises. I am really disappointed how they treat me as I am a loyal customer for more than 15 years. Think it's time to move on.
