Home Equity Loans Arizona

I bought a home several years ago and there was a bait and switch at the closing. The mortgage company, DHI Mortgage, slapped me with $300+ per mth. of PMI and I was stuck. They assured me that the PMI could be removed within 6-12 mths. They sold the loan to Countrywide and they did remove the PMI, but without my knowledge put it back on several mths. later AND took the payments out of my escrow acct. which caused my mortgage to skyrocket from $1300 to $2900 a month because they said DHI never paid the PMI – even though I paid it every month. Here’s the catch – DHI never disclosed any terms of the PMI to me at the closing AND I have in writing DHI admitting this. In other words neither mortgage company has a signed disclosure from me about the PMI but Countrywide refuses to take it off and think they can supercede Federal Law. My home was appraised in 2005, and the value is way below the 80% mark which is the guideline for PMI in the first place. Now I am in finacial ruins. HELP
