Pathetic Service

Highly disgusted with service from Vodacom. I have four contracts with Vodacom and need to upgrade one for my daughter, when requesting a contract of R259 with airtime that can be converted to data as teenagers use social media and don't phone each other, I was told that due to my credit rating I unfortunately do not qualify for such a contract but I do however qualify for a contract with 100 talk minutes and 1gig of data at the cost of R309...please can someone explain that special kind of logic to me, I am highly confused? I am trying to save money and cut costs, but apparently Vodacom thinks that I should pay more and on top of that for something that is a complete waste. But then again I am not holding my breath waiting for someone to actually resolve my query as according to the call center agent even if he escalates the problem there is no one that will actually phone me back, so the call center are a law unto themselves with the highest authority and ability to make decisions in Vodacom. All I ask is for my contract to be upgraded to the following R275 airtime and a Vivo Y21s phone @ R259 per month...I am sure there is someone at Vodacom that can press one simple button. PATHETIC
