3 Months query still not resolved

Dear Telkom, I have been logging a billing query for the past 3 months for incorrect biiling of sim activation fee of R200. The contract stated clearly that there isnt a sim connection fee but the useless employee of Telkom charged that on my account. I have for the past few months been complaining abt my unattended query. On the 25 April 2016, I got an email notifying me about my query beibg resolved, then I received my April Statement dated 1 May not reflection my credit amount of R200 . I feel that this is really ridiculous. I will be handing the case over to ICASA cause u have failled me ad a service provider
