Vodacom. Zero customer service

I am due for an upgrade. I have been trying to get somebody/anybody to help me, since mid. December 2015. I have contacted Vodacom Liberty Midland Mall, still waiting for sales person to get back to me. I have contacted Vodacom Hillcrest, still waiting for sales person to get back to me. I have contacted Vodacom Westville, still waiting for a sales person to get back to me. I have called Vodacom direct on countless occasions and simply get pushed from one person to the next by *********** staff. Last friday I finally spoke to a person who I thought was a pleasure to deal with and sounded very helpful. Or so I thought.... I'm still waiting for any feedback. I was so shocked to speak to someone who was helpful, that I didnt catch his name. This is absolutely shocking and frustrating! I have been a customer since the beginning of Vodacom and this is how I get treated? I get dosens of ******* spam calls from Vodacom and their partners trying to sell me *******.But try and get any joy when you contact them. Impossible. This matter better be resolved ASAP or I will be escalating this complaint and possibly moving to another network.
