Thee most inconvenient service provider

I at 1 point was a firm believer in vodacom as a cellular service provider but not any longer after what I've been having to go thru for the past 4-5 months! I have a 2+2gb data package, which I was totally unable to fully access let alone enjoy. My service had been suspended December 2014 & then only managed to gain access 2nd week of January 2015, which was absolutely non beneficial with a mere week & half until being suspended yet again to this very day with a remaining data balance of 3.5gb accumulated . After making a few inquiries is when we learnt that all the inconvenience had been due to vodacom being unable to trace my payments within their system which lead to numerous proof of payments forwarded to them & still no joy! Now for the cherry on top of all that I had been informed that my no. Had been removed from their system completely, meaning more cost to me and no service from vodacom. Nevertheless I purchased a sim & failed to activate it over the past 5days with countless attempts with customer care. Finally yesterday had been graced with a bit of good fortune there was success in getting connected with a measly 400mb. I HONESTLY EXPECTED SO MUCH MORE FROM V.S.P
