Bad customer care interaction

I received the worst service within minutes of receiving great service - all this within the same company. Salesperson Thobeka was great and I was looking forward to using their services. I then got 7 missed calls ***) within 2 minutes from a scheduling consultant named Nikita. This happened while I was in a session with a client. I took Nikita's call, she was so rude and insisted her call is an emergency that requires urgent attention.
