bounced debit order/bad service

After being asked so many times by telkom to switch to debit order i do so,when setting it up with them i tell them i get paid on the last day of the month so the debit will have to be on the 1st.On the second month i get debited on the 26th and now my account is suspended and if i try call them they tell me its suspended and it cuts me off.So how do i rectify this?<br> To add insult to injury i had no internet for 4 days last week and now another 4 days this week,this was the reason i was phoning telkom only to find that ontop of the 8 day no connection fault i have,even if they fix it i still wont have a connection because they dont know how to set up a debit order system date on thier side.i will now cancel my debit order and my connection and get the afrihost datastick.i cannot bring myself to going through these issues with telkom anymore its to frustrating and stressful to deal with them,i would be embarrased to say i work for telkom.
