No assistance received!

I contacted Telkom in February to cancel a line. I held on the line forever initially to even speak to a consultant who gave me an email address to send the request to. i sent the email and it bounced back as the mailbox was full. I then phoned again and was given the email address of a supervisor as they would attend to the cancellation. This morning i have contacted them again, after holding on forever again only to be told that the line was not cancelled and is still very much active and that i have to phone another number to cancel the line again! This is absolutely pathetic.
