receiving emails sender getting \undelivered messa"

For almost 7 weeks I receive emails but the senders get an undelivered message resulting in many phone calls from them ie. Vodacom, banks etc. thinking that I have not received my statements plus friends from around the world with the same concerns. 2 reference numbers CLOSED without anyone contacting me from Telkom. I received an email after the last Hello Peter post asking for my phone number so they could investigate- so far nothing. Call Centre assures me that I will receive a phone call from Telkom within an hour of reporting the fault. NOT TRUE. I now have a 3rd reference number *** and NO ACTION. If anyone is thinking of using Telkom for ADSL forget it and go somewhere else as clients are not important and obviously they don't know how to fix faults on their system.
