Bad service and poor communication

I had paid twice for the same item. Once with my debit card which the store manager deemed unsuccessful and later with cash.<br> Went to my bank and printed my statement which showed that the initial transaction was successful. Been trying to get my refund back and went back to the store to enquire only to find this person who made excuse and did not want to take the matter into their own hand and try find a solution. As i was talking to her, she wud jump in before i was done putting out my concern to a point that i had to tell her that what she's doing is not very pleasant. <br> She did not want to take my details or quary. Telling me that she wont use her personal phone to resort wat is a birden to me due by their faulty equipment.<br> Had to go back to the same store three times and still no solutions and i always get the same reason that their system is offline. <br> How are they meant to operate when their POS is never running? <br> <br>
