Telkom Direct

So after waiting forever for the telkom LTE call centre to make contact with me I decided stuff it I am going go to Telkom Direct in Canal Walk. I went there to sign up for the LTE package including router. The agent tells me he cannot make a sale because he does not have stock of the router I left my details for a call back. I was never called back. So I decided I will just get my own router. So I went back to the store with all my documents only to be told my bank statements need to be stamped by the back. Please Telkom get with the times who still requests stamped bank statements when clearly I got the bank statements from the bank atm. Not to mention I am only buy ing a sim card its not a contract its a month to month. I left all my documents with Lyle at Telkom Direct and I emailed him my stamped bank statements. I tried calling but no one answers Telkom why can't you sell me a sim card ?
