Withholding of Funds with no reason

Worts company to handle your transfer of a property, Transfer took place a week ago. Proceeds that are suppose to be paid to me after transfer hasn’t been paid to date. I’ve sent an email and phoned no one is responding regarding this matter. I guess they not paying, they are now playing hide and seek. Worst service I’ve ever received. I’ve asked for a statement of account in the invested account and they not saying anything.
