Billing problems

I was helped with a immediate cancellation of my rain 101 pro so tbat I can get the normal rain 101 i and a 7 day payment plan promise to pay active and you guys did give me a CreditNote of R545.79 and then I paid R253.21 cash however this amounts are showing on my profile but not allocated to my 7 day payment plan promise to pay and now it's stll showing as outstanding and now it's preventing the sales team form doing a new order can you please properly allocated to the payment plan balance. Because The outstanding balance remains incorrect. Please icorrect the payment allocation on the 7-Day Payment Plan it should be on 0 and my account should be up to date and the payment plan removed so I can order the correct product as I need internet urgently
