Telkom SmartBroadband Uncapped Wireless

Had my LTE for 3 weeks now, first week was AMAZING, was getting around 80 - 90mg download could watch twitch.tv on 2x computers on SOURCE and still Youtube on 720p on the side with no lag. Since last Friday 4th March it doesnt go passed 4 meg download regardless of time of day. Cant watch Youtube alone without buffer. Logged a call (Actually i have logged 4 calls all with REF numbers, spoken with 'supervisors', been told that i should reset my router , as if that will magically fix this service), but i guess that doesnt help either. They cannot even tell me which base station i connect to so i know which side of the house to put the external antenna. Went into Telkom, waited 45 minutes in the line just to be told 'Sorry, you need to call the call centre as we do not deal with the LTE packages'. Another 45 minutes waiting time trying to call their call centre EVERY DAY. I have reported this EVERY SINGLE DAY for the passed week (Online, On the phone, on mybroadband, NOBODY responds, same story every day 'We will escalate the matter' . I am paying a big amount for a pathetic service. DONT TRY AND SEND A TECHNICIAN AS HE WILL NOT BE ABLE TO DO ANYTHING, THIS IS A FAULT FROM YOUR SIDE!
