Rude and condescending tone from Tabitha in Upgrades

I called to Vodacom upgrade center on the 29/01/2020, to cancel my upgrade order as they were taking their own time with calling me back to confirm my order. I spoke to an agent by the name of Tabitha, she was rude and had no patience for me. I was frustrated at the Vodacom 4u store as I wanted to do my upgrade there and then. she cut me off as I was speaking and using a sarcastic tone with me. not only that, she was also very rude to one of the friendly employees at the Vodacom 4u consultant in westgate. Tabitha, you will always come across frustrated clients in the call center, no one wants to deal with a person that sounds like they don't want to assist and to top it, with a very condescending tone. fix yourself dear Tabitha, many would like the opportunity of doing your job with world-class customer centricity.
