Poor customer service: awaiting refund for a month

I have raised queries regarding an order placed on vodabucks store. The order was status was pending for some time. I called in a few times and kept getting passed on to different departments. Eventually I was assisted by Anastacia who is a team leader in the loyalty department. She advised she will call me back after investigating. She did not. I called in again and advised her that order was canceled. She advised she will call me back in 10 minutes. She did not. I called in again the the following day and she advised that there is no stock. I questioned how is this possible as orders for the same product was placed after and these orders were received. She could not answer me. She said she will get them to refund me. The refund was not done. I called in a few days later and spoke to her supervisor Ishmael. He assured me that the refund is being processed. He was also rude in dealing with my query. To date, I have not been refunded. The order was placed on the 18th of November. I was advised to check for the products on black Friday but my money was still not refunded. The fact that the employees **** and so dod the team leader and supervisor, makes me question the integrity of Vodacom on the whole. Extremely disappointed as I have been a customer for years.
