Billing problem

[Lilyan Arcana]

Hello,
On january 15th, I abandoned two 512 sqm lands for to buy 2 others lands from Murdoch (512 sqm each, so same size).
On january 17th, I sold one land (512 sqm) to Joseph Lowenhar before to buy 1 other land from Linden (512 sqm).
There was no increase in sqm, never.
But my invoice on february has increased : I paid 149,50 USD (125 without VAT) instead of 89,70 USD (75 without VAT).
I called the billing department who said that I should open a ticket for claim.
How do I apply for a regularization ?
Thank you.
