Extremely poor turn around time.

I gave birth on the 18th of Jan 2016 and sent an application to add my newborn as a dependent on the 21st of Jan. I called a week later to follow up as the automated response stated that i would recieve feedback after 3 working days, which wasnt the case. I was told that my application wasnt recieved. I sent another application via fax and email, after a week i called to follow up and i was told the same story about my application not being recieved. I've sent another application, followed up last week and was told my app is with the underwriting department and i must follow up on the 16th of Feb. I called today to follow up and was made to hold the line for almost 15 minutes. This was the final straw. Ive sent numerous emails to email addresses that were given to me by these call centre agents, all of which bounce back as the email addresses do not exist. This was the final straw. I am cancelling my membership with Hosmed and have desuaded friend, who is an HR Executive, from using Hosmed for her company's employees as a result of this inefficient service. Its extremely frustrating to have to not recieve timeous feedback and have no channels to escalate issues to.
