L Gerber, Melkbosstrand
I experienced the same problem of not receiving Telkom accounts via email recently.
After the third month of phoning and their call centre forwarding my account, I was asked whether I was an MWeb client.
I was told that Telkom had found that it was mostly MWeb clients complaining and that the subject-line wording in the Telkom emails was for some reason causing MWeb servers to read them as junk mail.
She asked me to contact MWeb. MWeb then sent me an email showing me how to change my settings through the MWeb website so that it doesn’t block Telkom and also to retrieve my earlier emails. I did this and problem solved.
