Very slow internet speed

I took out a MTN data contract a while ago for which I pay R699 a month. Please do not bother with any data contract with MTN. Very slow internet speed is at the order of the day. I have less than 0.8 Mb download speed. You can see WhatsApp text but that is all no video or pictures. It is a pity that these large corporations take advantage of the public so much. Imaging if I decide to break the contract we signed. Imagine if I decide to stop paying... Surely they would take me to court but the other way around and nothing will happen. Please be vigilant rather go for another inter provider.
