Disgusted with Edgars customer service

I have been trying to speak to an agent for the past two weeks regarding settling my Edgars account which has been handed over to a third party agency. I have called all the numbers I could find on Google and only one of the numbers have been answered. I spoke to an agent last week who kept me on hold for longer than 20 minutes while she searched for the contact number of the 3rd party agency, during which time I had to drop the call as I have been waiting so long. I sent an email to 'edg*******' and have not even received an acknowledgement response. I am at my whits' end as I would like to settle the account and close it .
