5 Months to sort out simplequery and still waiting

In October 2015 I logged query to have a credit for Quick Sim insurance from the day I joined Vodacom 15 years ago. The reason was each time I had a sim swop I still had to pay for the R150 fee, which is suppose to fall away if you have sim swop. <br> <br> I have still not heard anything back other than 'we are still working on it'. <br> <br> This is unacceptable. I have already cancelled 1 line on my contract, the others will follow as they come to an end, one by one, till I am rid of Vodacom
