poor service

I was in the Pinetown area and decided to stop and purchase some electrical supplies. I made my purchase and went to the collection counter to pick up, press the bell to bring to the attention of staff that I am there to pick up my order. When I press the bell employees looked at me and did not respond so I waited for 15 minutes and nobody came so I went to the sales counter and asked to see the manager. The manager who was sitting in his office right in front of me all the time I was waiting came over. He asked a staff member to assist but I requested a refund and was refused because they had some story and said will deposit the money into my account the next day which did no happen. After many phone calls over a week I finally got my refund by a delivery driver to my house in cash. Promised myself never to go Voltex again.
