billed for something i did not apply for

i have logged a complained with Telkom ever since i did an upgrade on my line but up until today no one has assisted me. now the new development to my case is that the log no's that i was given there are not on the system meaning that they **** saying that they did.(***)<br> i am really tired cause all the time every month i have to call them and i do not get a solution at all from them.<br> i am truly mot happy about this as i keep on sending mails to the branch manager at Maponya mall and he has not responded as yet and its now got into a point of me getting frustrated that i am not being assisted.<br> i cancelled my spending limit when i renewed but when i get the bill its is high like when the time i had it. when i went to the store to enquire they said that on their side its not there but on the billing its there. now whop must i believe. <br> i paid the 1st amount due but the 2nd month again it was there. now on the latest invoice that i have there is some credits on the account which i do not know what are they for and no one can explain that to me. please call me on my land line *** or my other no ***
