Wendcal properties holding rental payment to owner after using rental amount which did not belong to them!!

Monthly rental for the month of March was paid to the Wendcal properties account by mistake by the tenant instead of using my account details. We’ve been asking Calvin the owner of Wendcal to pay the rental into the correct account since the 1st but to date he has not paid, not taking our calls and not replying to our messages. Such unprofessional behaviour and service from Wendcal properties!!
