Incorrect billing

Dear Telkom, I have 2 sim cards issued on my name of which I have been paying for since November last year. I only have 1 sim card thats in my possession because your employee from Cornubia branch in durban did not know how to issue the sim card to me and had trouble doing so but instead she has issued 2 sim cards which i pay R100 each. I have sent an email regarding this on the 27/03/2019 and have not gotten any feedback of any sort. I would like to request a refund for this sim that I do not have or I will report to the ombudsman from here.
