shocking overcharging

<p>I am a customer of vodacom for more than 20 years and have 3 contracts with Vodacom. My cellphone and 2 data contracts. Both my data contracts were fixed 2 G contracts. At some point earlier this year I got this high billing and phoned vodacom to enquire. I was then told that the 1 data contract was an open contract. I then stated clearly that I never asked for an open contract and that it must be fixed again at 2G as per my original contract. In good faith in believed it was done until I received my billing this month R2500. Upon enquiring again I was told that I have an open contract and that I was billed according . Upon investigation I saw on the tablet usage that we went over with 1G at a cost of R1500. .....still no apologies of the error on their side. So I had to pay R1500 for 1 G that normally would have cost me R149. Day light *******. I am clearly thinking of taking my business elsewhere</p>
