Incompented Agents

I phoned yesterday 29/09/2015 to get the settlement on this Telkom account. I made an eft payment yesterday morning in the amount of R250 like always, when I phoned the lady/ agent told me to settle this account upon the R250 that I paid that morning I must make a further payment in the amount of R560.15 to settle. I must phone tommorrow the 1/10/2015 to confirm if the payments is reflected on their system,and to request a paid up letter. Now today 30/09/2015 I recieved a sms that states a further R36.91 is needed to settle this account.<br> <br> Im really upset, why did the agent do not give me the right amount to settle this account.<br> Or where does the R36.91 comes from in a days time after I settled this account????<br> <br> I made an eft payment for the R36.91 and hope it's the last amount!! <br>
