Telkom - No support/service

I have called into the contact centre on numerous occasions to change my debit order details to no avail. I even went to the Telkom store to update the information and was advised that they are not able to assist as only the contact cenre can link it. I would like to close the old account that you have debited from but cannot as the debit has FAILED. <br> <br> These are the steps I have taken to correct my debit order details:<br> <br> - I have called in to the contact centre on numerous occasions to update my debit order details (UNABLE TO ASSIST)<br> - I even went into the Telkom store to have this updated (UNABLE TO ASSIST)<br> - I then emailed Telkom with my complaint but received no response (UNABLE TO ASSIST)<br> <br> I have emailed them again today but was prompted with a message 'Delivery has failed to these recipients or groups' as their mailbox is full and I should try again later.<br> <br> Ironic for an ISP to have their mailbox full.<br> <br> I am extremely dissapointed in the service (or lack there of) provided by a company as huge as Telkom, which is supposed to be South Africas leading telecommunication company. <br> <br> All I would like is for my debit order details to be updated, is that too much to ask for?<br> <br>
