Vodacom trying to overcharge me for the 2nd month in a Row

<p>Vodacom advertises that they give you free 10gb if you sign up for a new contract so I took one, now I see Iam owing double what I usually pay monthly for my contracts look at my bill and it says I owe money to them for that 10 gigs like I got a new contract on both my sims however I only received one 10gb of data?? </p> <p> </p> <p>Please any customer of Vodacom keep a super close eye on your bill. This is the second month Vodacom is trying to overcharge me after they sorted last month's and even called me to apologise for the so called glitch in their system and deducted the overcharged amount.</p> <p> </p> <p>Vodacom I expect a call from you very soon.. this Is bluesy ridiculous man.</p>
