Please update and coorect the information

I am disappointed that when I went to check my credit report I see that my monthly installment for my Telkom account is R1 109.00 where in actual fact I am paying R269 a month. This makes it look like I am having huge credit repayments which may deter potential future creditors should I decide to get a loan or credit card etc.

Please rectify this, it is a bad reflection against my name.
