Unpleasant customer service

I signed up on Tuesday 12 February for Greenpeace donations, and then I decided to cancel my pledge to donate.

I made a call today to cancel and I spoke to a lady by the name of Siphelele Dlamini, I must say she was very rude. She asked me for my reference number, I was not sure what she was referring to and I asked her where I get the reference number. She rudely explained that it is a number that they get on the confirmation email when pledging. I asked her if she can hold while I look for it on my emails and she gave a sigh of irritation. I asked her if cancelling is a problem because her tone is rather rude and she rudely told me that she is not feeling well. My response was that if she isn't well its better not to come to work because now she is being rude and unpleasant.

In essence all I am saying is there was no need for her to be rude, whether she is feeling well not her customer service should not waver and should not be unpleasant
