Ambushed?

My friend made it perfectly clear to RBK&C that he had no wish to speak to them or their contractors yet today, at 16:00, someone named Felicia called without an appointment demanding to speak to my friend. She left a calling card marked "This is urgent", yet the RBK&C contractor failed to turn up to an appointment LAST WEEK. If it were so urgent, why did they miss the appointment??? I shall keep you all posted on developments.
