Very rude Consultant from Telkom's Durban office

So I app**** online for a cellphone contract and a very kind telkom consultant (lady) called me and we agreed that we would continue the process on a certain date for them to debit my account. She didn't call on that specific date and I then unfortunately missed her calls from there. Couldn't return them as she advised me against that (it's a call centre and I will get a new consultant every time and they will go through the same process over again etc.). So long story cut short, we never got to speak again. Then today, 12 October 2018 at exactly 13:50. I receive a call from a telkom consultant (guy, from this number ********** 432) regarding the online application and I said unfortunately I changed my mind. He then rudely said "so you apply online and change your mind?". The I told him I don't appreciate his tone and he did that sarcastic "hmm" and hung up on me. I sympathise with the consultants for getting indecisive customers like myself but I did not appreciate his rudeness. Please do some quality assurance on this guy's calls; I'm sure there are a lot of people who would appreciate the job. Unfortunately I did not get his name.
