Shocking Service from Redefine Properties

My experience with Redefine Properties has been shocking to say the least. I concluded a deal for Redefine in May earlier this year and am still awaiting to be paid the commission due to my company. For the past 4 weeks I have been following up with their office for payment and get told that the payment will be made in the week, yet no funds have been received into my account. I receive no feedback and always have to follow up with them despite them telling me they will keep me informed. It blows my mind that something so simple can take so long when they have all my required documentation. It's a disgrace that a company of this size and who has been operating for many years conducts themselves in this manner. If this does not get resolved this week I will be informing many of my existing and future clients not to deal with Redefine as their staff that I have been dealing with lack professionalism and moral values it seems.
