1&1 Internet Charged my card and still won't refund me other Pennsylvania

On January 17th, I got notice of hosting renewal for $95.88. Prior to that, I had only gotten domain renewal for $15.17. The notice for hosting said my card would be charged within 7 days. I did not want to renew the hosting, only the domain. I logged in to my account and removed auto-renewal and also emailed letting them know I only wanted to renew the domain. On January 22nd, my card was charged $111.05. I asked for a refund of $95.88 three separate times. Over a week after being charged, I filed an amount dispute with my bank. 1&1 still did not refund me. I was finally issued a credit invoice on February 16th for $95.88, but did not receive the refund. Then, on February 20th, my card was charged for $15.17 for the domain, citing failure to pay. The charge for $15.17 was refunded (after multiple complaints). I am still waiting for the $95.88 to be refunded. I have received every excuse imaginable, including the "Solutions Manager" telling me on March 2nd that they had trouble processing the refund because I filed a dispute. He told me "that a dispute ceases all interaction between 1&1 and the card on file". If that is true, how did they both charge and refund me the $15.17 after February 16th on the same card? He also told me I would hear back on March 5th. It's now the 8th and still nothing. This has been a 7 week nightmare!
