Phumzile from MTN billing horrible and rude!

My husband requested that they cancel the extra 1 gig on our contract and we even got an sms that it was cancelled . Today we got another sms that the gig is reissued we phoned around pass 7pm and Phumzile who sounded bored and annoyed is telling us she can see the cancellation nor the extra gig which is fine if she can't see she can't see mos neh!then we ask for a way forward to cancel and she says we need to go to the store and obviously annoyed! Honestly MTN call center agents are rude and the lack of product understanding is concerning and annoying 'coz they also clearly hate what they do and disrespecting customers is a norm and that is if you get to them 'coz they also place calls on mute. MTN wake up it's unacceptable that bad service is a norm!
