Bad Telephone ettiquette

On ********** 9 I called ********** 925 at 11:17am spoke to DUDU in the customer experience department. I asked her what my available balance and whether there was a pending purchase pending on my account. She initially gave me an amount then said I have to speak to thee Accounts department, then I asked if she gave me the incorrect information then she carried on speaking over my voice that no:1 is BAD telephone etiquette then she goes into a sarcastic tone when at this time I was long over the 1st question and was asking her a 2nd question to assist me with an online purchase I was attempting to make but my OTP was sent to my cell and I was at work didn't have my cell on me wanted to know if it can be sent to my work email. 8min4sec later she says that cannot be done she wasted my time and she immediately changed her tone thereafter I reprimanded her customer savvinness. Unacceptable. The worst telephone experience with an agent representing such a well known Retailer!
