Bad service and unresolved issue

I called Telkom this morning regarding my account and debit order. There agent I spoke to last time gave me wrong information now Telkom wants me to pay a debit order fee of over R200. I wanted to cancel my account because I'm unhappy. Spoke to Shannon Klassen regarding the matter, the lady was not interested in my issue Nd became very rude and telling about other service providers. I'm so disappointed in Telkom and I would like for them to reverse the charge. Or cancel my contract Nd go our separate ways because the service im getting it's sad for me I trusted Telkom but this always paying extra even last year they messed up dates I had to pay but they fixed that one. Was very dissatisfied with the service from Shannon Klasson
