No customers wanted!

I wanted to see what othe options where available as I have 1 month left on my Telkom contract, at 17:30 I was kept at the entrance of the store with various queries by an Assistant of the Tellers, as they wanted thier assistant to help me with my last bill instead of a new contract. I didnt need help with my existing contract, I wanted to get a new one, I had my latest bill with me as well as my ID card, but was told to call the call center rather??? I asked what is the best way to go about this as I also had a query about how the billing would be, I was advised to come on the last day of my contract, but my bill does not show what day that is, the Teller advised thier assistant at the door that I could not speak to them directly. I suggest that proper Customer training should be put in place, especially for soon to be ex-customers...
