Telkom Mobile Personal Data Infringement

Hi Telkom mobile My account number is ********** 05. My name is B Williams, my contact numbers are ********** 809 and ********** 216. I have got a major issue, I believe it is a case of intellectual property right infringement and personal information invasion which is one of the major crimes in SA. My contract bundles are as follows: 1. Telkom uncapped mobile data for R899 p/m 2. Freeme 1gb contract with a P20 lite for R269 p/m 3. Freeme 1gb contract with a P30 lite for R299 p/m My sim card when installing whatsapp with verification code comes from Capitec Bank (Verified from true caller). I do not have a capitec Bank account. Also when searched online, it is verified as Capitec Bank. I received my contract on 15th February 2019 for the P20 lite and only installed whatsapp on 25th May 2019 yet there was already chats on this number and a profile picture. This shows my number has been used before without my knowledge. This is only one of the issues. When logging onto the Telkom App, my uncapped data contract is listed with 2 Sims and one number. This is a major problem. There should only be one number and one sim. Why and how did this happen?? According to the Telkom store this is a major security issue which I was told yet there it is on my account... Please call me on ********** 809 as this is not acceptable and I need answers today otherwise I will be taking this further. This is a urgent matter and we have already done a number change and this is not what I would expect from the top network provider in SA. I trust this meets with your approval. Mr B Williams
