Very bad customer experience

DSTV services keeps getting worse by the day. I received shocking service from a girl called Ntomboxolo working the night shift today the 1st of August. She was very rude with zero etiquette. She literally put me on hold to laugh in the background (Waites my airtime for 20 minutes). Please can a manager call me back tomorrow morning at 09 AM on ***. I wanted to downgrade my package to Access. I was told that I need to pay almost R300 for a mistake DSTV made 2 months ago when they gave customers discounts. If you give discounts to your customers in errors, why should your customers pay for your mistake? Please call me back to resolve this tomorrow, in the meantime, I have made a payment for the Access package.
