Poor Customer Service

I regret signing the contract with Neotel as they false advertise.Customer service is poor,network is terrible and the network is too restricting as I can not use the sim card on other devices.I checked their website for network coverage as the consultant told me to do so and it showed that my area(Chatsworth and Montclair) was covered.The speed is damn SLOW(slower than a snail) as it takes days to download a small 100MB file while Telkom downloads it in few minutes.I have a 10GIG contract but the speed is slower than an uncapped contract.I saw an advert on their website to double the bandwidth speed between 6pm and 6am but still the speed was the same!Open wifi networks in the mall are faster than this!I am using a 3G ****le but the speeds are 2G which seems like Neotel is going backwards instead of going forward.Their customer service is terrible as I have to wait 2 days for a reply and now I am stuck with this useless network for 2 years.
