Is this shocking level of service even possible

Had the most shocking experience at Benoni Trailer Boys Branch. We have rented a bike trailer for six days, this morning we responded to a whats app message confirming that we would be collecting the trailer during the course of the morning. My Wife receives a call from an obnoxious staff member informing her that this trailer is in HIGH demand and if we don't come and collect it he will rent it out, notwithstanding we have paid for the trailer it's 10am and who the hell is he to call and demand her presence, if we leave it there for six days that's our decision, My wife informs me and i arrive at the offices on Great North Road to be met by the sales assistant who merely shrugs it off as a miss understanding. I demanded to speak to the owner and he would only offer his email address as the owner forbis the giving out of his number. you can see that the fish rots from head at trailer boys. I absolutely lost my temper and they will never see my business and i will share this experience far and wide.
