Telkom CRESTA, worst service I have ever received....

Telkom CRESTA, worst service I have ever received. Young, unknowledgeable and have an attitude. Very disappointed. Went in with 81yr old mother to get pensioner rate on landline with the new Wi-Fi phone and they couldn't help us. Were too busy laughing & chatting among themselves. Came away with no help offered. 10123 are just as unknowledgable, get pushed from pillar to post.

Does anyone know how we go about getting the Pensioner rate? Or who we could approach?
