HUGE REDICULOUS BILL AND NOT EVEN A FULL MONTH OF SERVICE!!!!!

My Lines were only installed a month ago, I have 2 uncapped ADSL lines, 10 mbps, how is it possible for my bill to be R4000? I am being billed for a TIN297.... which I don’t even have a service on, no line, no internet? And the address for this TIN is 59 Hertzog street, Vanderbijlpark?? There is a company linked to my number 053...…., Tiger ….. on TIN297.... and it is on my account? I am being billed for someone else's usage!!! TIN336.... and TIN349... are my numbers 011 ….…. & 011 …….., what is TIN297....? I am being billed so many Home Uncapped 10mbps and 4mbps???? And so many DSL faster and DSL fastest? I don't know what is going on with my account? Telkom has put me through SO much nonsense with the installation and relocation of my lines, billed me when I was still waiting for my lines to be installed, and NOW a RIDICULOUS bill of R4000????? What is going on?? I am trying really hard to be patient....... there is no way that 2 10mbps uncapped ADSL lines cost R4000, and my lines are not even in a full month as yet??????
