Delta Dental Plans Association review: Worst customer experience ever with an insurance company!!!

If I could leave a 0-star rating, I would! I have never had such horrible customer service other than retail / restaurant experiences. Their communications with their customers SUCKS! I had an email telling me that I needed to pay for two months and that my account would be suspended. I called the customer service number and was told that my payment went through and that I did not need to pay anything. The next week I get a letter in the mail stating that my account had been suspended> called their customer service number and inquired about this and was transferred to a supervisor. The supervisor told me that if I had the money in my account, they could reinstate it. I affirmed with them that the money was there, and they told me that someone would get back with me by the end of the day to confirm that my account was back in good standing. 3 days later I had not received a call and went to the website to see if I was still suspended and was unable to see anything as the message I received on the website was that there was no record of my account. I called their office and was told that there were people working on getting my account back in good standing. When I asked why no one had called me, I was told that it would take up to 2 weeks before my account was back in good standing. Today I called them and was told that they mailed me a letter two days ago telling me that they could not process my payments and that I was now locked out for a year for coverage with them. When I asked to speak to a supervisor, they told me that they had "left me a voicemail telling me that they needed to talk with me". When I told them that I had never received any voicemails from them, and questioned when they made these calls, they were unable to tell me, just that there were multiple calls left on my voicemail. When I questioned them and pushed them further, asking for clarification and a record of when they called, they hung up on me! This is very poor customer service! Their lack of communication and horrible customer service, lying about contacting me in any way to let me know what the status was or to let me know that they were having any kind of trouble processing the payment tells me that there is no communication and apparently their staff lie to cover their [censored]!
