Unexplainable delay and very difficult communications

In December 2025, I paid 335.20€ for 4 items (000101227 (boom 180-230 + 3 Unifiber Mastfus Baseplate). You have the copy of the bank transfer, transmitted to you on January 14, 2026 (INTER20251229BOSBE617477654. My IBAN: IT44U0306916326002600000448).
On February 2, 2026, I received 1 item (boom, price=132.85€).
After more than one month, I am still waiting for the reimbursement. Please provide me with the reimbursement of 202.35 € (335.20-132.85=202.35). The details of my bank account are provided in the bank transfer I did and above. I look forward to hearing from you.
Kind regards
