Complaint - Vodacom

I went to Vodashop to wait for the technician. I was quite relieved to see that for a change they weren't so busy. Three ladies were helping one customer, and I was told to take a seat and wait. I just waited for a minute or two and then decided to leave. How can they let a customer wait while three ladies were attending to one customer? There is only the one Vodashop at the mall and is normally quite busy. That is why I was so relieved to see it was not so busy. I am not happy with the setup there and think I will definitely change my supplier when this contract expire! Ann van Eeden ***
