Pathetic after sales

Absolutely ******* service! I've been trying for 3 months to get my account sorted out due to Vodacom adding device charges to my accounts. They sort out 1 part of the query but not the other and now my line is disconnected. Every time you try to talk to someone they either promise 7-14 days to sort the query or the line disconnects. I've spoken to so many different people and departments over the last few months that I really don't even know who I actually have to speak to concerning this! I didn't even get a device to start with so how can you charge me? Latest is that payment arrangement due to your incompetence will 'hopefully be sorted by the 15th of October' and then the line disconnects. I should have completed my cancellation when I had the chance. I've been with Vodacom longer than I can remember and never missed a payment, I'm even paying my normal installments through all this and this is the thanks I get. Thank goodness I cancelled my husbands account with you guys when I got the chance. MTN scored a new customer there
