When you call to remove a thee it only gets remove ON THE FIRST DA OF YOUR NEXT BILLING CYCLE...
If you call let's say the 13th and your biling cycle is from the 10th to the 9th... You bill, which will cover from the
10th of September till the 9th of October...since it is printed BEFORE we remove the theme (on the 10thof September) the bill will show the charges for the hole programming, including the theme you asked to be removed. Once it is actually removed, theamount of the dropped theme is then credited.
If you got interest and late charge that means you decided NOT PAY THE HOLE BILL, not just the part you were disputing!
