Absolutely useless!

i have been trying to contact the call centre to amend my fathers account for 4 months now. He is a pensioner but they messed up his account and is no longer receiving a pensioners discount. Every time I call they either tell me it will be sorted on the next bill or I never get through to the call centre. When the bill does come there is no discount. I wonder if these call centre agents are literate as they can't seem to process a simple request. Honestly, neotel seems like a better option at this time. Telkom customer service is atrocious!!!
