lack of customer service

I went to Pep home to pay my Dstv account and the the cashier helping me had a very stinking attitude and didn't have a name badge because I had to get the name from the till slip. From me coming to the counter she had a frown from hell with a hideous hat on her head,whilst assisting me I made a mistake on the total amount I had to pay and all hell broke lose. I told her I made a mistake with the amount and that's when the evil look came out then she insisted she's done with transaction while she still had my debit card in her hand and hasn't inserted the card in the speed point. She clearly has no customer service and very rude, if she doesn't want to work there she must just go lot's of people are looking for employment.
