Cancellation Nightmare

Trying to cancel a order is a nightmare. I cancelled the order in email. Received a response I need to wait for a call. Received the call. I made it clear I want to cancel as I have enough product. She did not listen and kept going for more than a half hour. I again repeat my cancellation. She ignoredme and was going on trying to persuade me. I end the call. I immediately emailed their customer service and again wastold I need to wait for a call. I then phonedHead Office and again she didn't lusten and said I will receive a call. I refused to rake more calls.
