ACCOUNT IN CREDIT - BUT MY LINE GETS SUSPENDED

How can Telkom deduct a debit order off my account for R824.00 (13 Feb), even though I only owe them R545.80, and then after my account is actually in credit because of the above, then suspend my account??? Now when I ask them if they are going to refund me for not being able to use my phone for the past 2/3 weeks, they say NO, I should have called in to report the problem. <br> <br> I have 6 separate accounts with Telkom, and this is the way I get treated!! Will definitely NOT renew my contracts as they come up for renewal. I'm sure there are other companies who are more willing to have my business and actually accept and acknowledge if they made a mistake.
