Disappointed

The is an authorized debit that went off my acc . When i ask whats is for ur consultant Thato mothupi is tell me that its for discovery miles . And she was uninterested in helping me and was also rude I activated my miles on the 6 june ...i made provisions for it in july no debit went off .. now in 6 aug it was billed..why wasnt i informed of this...THIS is what i ask of the previous guy who called me and he couldnt tell me .. next thing i see a set off my account.. i didnt refuse to pay i wannted explaination which no one wants to give me .now im debit an amount that was for my food in the house. Just because ur agent cant prob or negotiate with customers doesn't give them the right to do a set off..this abuse of power ID 821 ********** 084.
