LTE solution not delivering promised speed

I responded to an advert in early October 2015 for the LTE Home Solution, which stated that the solution would provide connectivity up to 90mbps.<br> When the field tech came to my house, she said that I was getting full signal, and that I would definitely get 90mbps. I cancelled my ADSL line and bought into the offer. A week after getting the new router and SIM delivered, and after thorough speed tests, I can confirm that I am NOT getting anything close to 90mbps...in fact, I get 30mbps on a lucky day.<br> I then shortly thereafter, went into the Telkom store in Clearwater, who informed me that I could get a booster antennae (not sure what the hell that is going to help, considering I already get FULL signal), but decided to go along and log a call. This call has been sitting with Telkom from 13 November 2015, with several updates, each update having been 'attended to' as it's status, even though I am yet to be contacted back by any Telkom employee.<br> I am well within my rights, according to the CPA, to cancel my contract (2 year), but I don't want to - all I want is the promised speed connectivity!!!!
