Unprofessional, does not keep appointments and does not call back despite repeatedly making promises to do so.
On Sunday, through a contact form expressed interest in a home with a request to schedule a viewing. Called the next day to ask when we could get a response, we would be called the same day. Didn't happen.
3 days later contacted again, again no broker present who would speak to us but a note would be made and we would be contacted before noon. After not having heard anything again, but called after noon, another operator on the line. According to her, no agreements can be made about when to call back, but I could certainly expect a phone during the week.
We are now more than a week later and a simple phone call in the meantime is apparently too much to ask. I understand that it can be busy, but you do not tell me that in 2 weeks a broker has not been able to take the time and effort to pick up the phone and make a call. Moreover, I find the repeated failure to keep promises very unprofessional and I feel kept on the line.
Although the perfect house would now be advertised, if it had to be through Stoit group I would rather stay in a cardboard box on the street.
