Unprofessional and pathetic service

I had made an appointment with an agent from Wakefields Chatsworth , namely Nisha for 22 October at 6 pm. At 6 pm on the day we had a no show, then at 6.02 I sent her a message and there was no reply. I tried calling her via WhatsApp but to no avail. At about 6.05 pm I called her and she answered, but to my shock, she informed me that she has to reschedule the appointment. I then enquired why she had not informed me earlier of this and why she waited for me to call her to inform of me her decision. An invalid excuse was given and an apology. This is the value that Wakefields Chatsworth gives to their potential clients and this is how professional they are in dealing with potential clients then one wonders how professional are they.
