Vodacom - Over promise, and under deliver

I am a very disappointed Vodacom customer. Been loyal to them for more than years.

Phoned Vodacom in May to cancel 2 lines of mine. I spoke to retention dept and they gave me good deals. So they convinced me to stay for another 2 years. The 1 line was converted successfully. That, I am grateful for. The other upgrade - since the 21st of May, I have not received my new wifi router, or ANY communication that I am upgrading the line. After MANY calls to Vodacom. 1st - they sent out the router to my OLD address. (they did not phone to confirm delivery - only saw email from RAM) that is when I called them, AGAIN! There was about 6 calls to Vodacom, just to update my address. Note - I have requested that, in call nr 1. We are now on the 1st of July- and I haven't received my parcel. After MANY promises from retention department, that it will happen. With my 1st call to cancel lines we got to spoke about my primary number and there was promises for data also promised on my line. That did not happen as discussed. Some services that was activated last month (June) for a period of 3 months, I see have been cancelled on my line, today. Why?? Now, Vodacom is taking back stuff that was promised and also not giving what was promised. I am just on the losing side - AGAIN. Very disappointed! I would like a senior Supervisor to contact me ASAP!
