Telkom giving me bad credit history

Good day. I have just pulled a credit report from TransUnion and notice that on all my Telkom transactions they reflect as 60 or 90 days late or in arrears.<br> <br> I only have a line rental with Telkom (for this exact reason) which is a mere R157 per month and furthermore this amount is on debit order and goes off on time each month. <br> <br> Could somebody please contact me to change this on my credit history<br> <br> Thanks
