No help at reception/teller

I visited the Vodacom shop at Nicolway on Wednesday 28 January 2015 to buy airtime. I was there at 11.10 but no-one was at the teller point. There was three consultants busy at the cubicles, but no-one made the effort to assist me or tell me where to get airtime. I waited for 20 minutes (the consultants was all busy during this period) when a Samsung worker entered the shop. I enquired where the person is that is supposed to be helping customers at the till point and he informed me that she was not in on that day. He ran to the office, stayed away for a few minutes and then came back to inform me that there is no-one that can help me. I buy airtime and data regularly and support you to make your money. Why do you not support me as a customer?? It seems that you do not care to assist the walk-in customers, but contract customers and customer buying phones are helped! I am also a contract customer (for the past 17 years) but also have a non-contract phone. This pathetic service (actually no service!) makes me think to either change networks and close my contracts with you. Customers are your bread and butter, but it seems you do not care about them. Please investigate..
