False advertising

I app**** for the LTE package where you get a Router .I was told that the "Uncapped" data works as follow. 150 GB data @ 10Mbps , Thereafter 50GB @ 4Mbps and then 2Mbps uncapped data for REST of the month. Well this is unfortunately not the case at this moment at my house. Surely ive reached data where line should be at 2Mbps now because of school holidays and kids at home watching tv whole day. My problem is that my line is not running at 2Mbps like i was told and like the advert said. My line actually running at a low 84Kbps. So i would like to know if this will be resolved as Telkom is now in breach of contract not giving me the 2Mbps that i am suppose to get and what i app**** and signed for in the contract. If Telkom can not sort this out please cancel my contract with you guys because you in breach of contract. Otherwise sort this out so i can get my 2Mbps like i'm supposed to get.
