Wrong Goods and Bad Attitiude

I went to Edgars in mall@reds today to purchase Telkom mobile airtime, I realised I was given Telkom landline airtime instead of Telkom mobile. I do understand as a customer its my responsibility to know what Im buying but i feel its more the staffs responsibility to ask me which type of airtime I want instead of just assuming, that should be part of their training. According to the Manager we were supposed to specify if we want Telkom or 8ta airtime but the cashier showed me there is only Telkom and Telkom Mobile on their system, also all advertising in store only states Telkom mobile and not 8ta. The worst part is the bad attitude we got from the manager Sarah. She was called twice to assist us but instead we had to walk to her office where we found her lounging and chit chatting with another staff member. That is PATHETIC!!!!! I work in retail so I know as a manager customer service and complaints should be your first priority. I refuse to accept the wrong airtime given to me as I have no use for it and I hope this matter will be resolved asap!
