SHOCKING SERVICE WITH NO RESULTS.......

In December I called Vodacom to do an early upgrade only to be told they did not have stock of the phone I wanted (which originally I was told there was stock). I called back in January and spoke to Kydi who promised to send me a voucher to pay off my handset which apparently needs to be done before they will do upgrade - she promised to call me back that was last week Tuesday - eventually I managed to speak to her again today after calling, holding on being promised for a manager to call me back on numerous occassions to no avail. After all that she eventually sent through the voucher today AND IT IS FOR THE WRONG CELL NUMBER attached to my account (unless the amount she gave me last week was totally different from the voucher she sent through today) The incompetence is just ridiculous and as a Vodacom customer after being messed around and treated the way I have I am so fed up as I am sure you can imangine and all I want is for somebody to sort this out without me having to be put on hold for 40 minutes at a time!!!!!!
