Lost a fortune because vodacom signal dies

I am sick and tired of Vodacom when my contract is over I am porting to Mtn. I just lost over R100 000 because your network goes to hsdpa when I tried to pull my stock before it dropped. This is the 5th time I am complaining and its fixed for a week and then this starts again. Vodacom can't even satisfy their own customers but they want cell c to ***gy back off them? You guys are the pits im emailing Shameel now cos I'm sick of this sh#&.
