Trying to leave (the Hotel California)

I cancelled my Telkom line before I left the country. I started the process in March and after having to resubmit the cancellation request a few times because they weren't responding etc etc I got a phonecall confirming that the service was cancelled with effect on the 24th of April. But then a debit order amount of R229.04 was taken off my account on the 25th of May. I have heard of many customers who have struggled to get Telkom to cancel their lines. I emailed the cancellations email address back to request that the money be refunded and my debit order permission be removed from Telkom. And guess what? The email kept bouncing back saying that the email address did not exist. THIS IS THE SAME EMAIL ADDRESS THAT I USED IN MARCH. THEY WERE QUITE HAPPY TO RESPOND TO IT THEN. I really want Telkom out of my life forever. If someone can arrange that refund and cancel my debit orders forever, I will happily write a glowing review of the customer service I received, but at the moment I am just joining the queue of people calling Telkom *********** and thieving. Please help, someone out there.

Thank you. Jessica
