Bad customer service at Detla Towers store in Durban

On 02 November at 13h30 I visited Telkom Delta Towers branch in Durban CBD, I was served by Zama Zulu who after I had explained to her I wanted to change a 40gb mobile contract I took the day before via a consultant who called me I now wanted 180gb also advised I called back the telkom line to advise of my request but they haven't gotten back to me yet hence I can to the store to check if my request can be actioned, with an attitude she said I doubt they did put a note on your new contract to cancel it and replace with 180gb, she took my ID assumming that she was checking if this was done she then proceeded to process an application while doing this she would answer only what I asked never given me information to a point when we were done I had to ask her the period of the contract she just said 12 months that was it, I also asked for multi sim cards she gave me 2 when I was expecting three she then advised she renewed my existing device contract. Days later I receive an sms that the contract I took online the sim card was being delivered clearly Zama did not check whether this was cancelled she just renewed my existing device contract. I now have 2 contracts with Telokom simply because Zama failed to inform me that she could not assist with the cancellation or amend my request. Her attitude was despicable even when assisting me it was like she was force to do it. For her to renew my device contract without addressing my primary query was an injustice. I'm now left with a burden to cancel one of the contracts. Her attitude and lack of assistance has should be dealt with by management, how does a store consultant do as they please on a customer's account without giving proper informatiom if she had just she could not assist with my query or request I would have appreciated that.
