PHH Mortgage complaint: Thieves

I have had a reverse mortgage since 2007 and dealt with about 6 different mortgage companies. Since PHH bought my loan last December 2021, they have done whatever they could to give me my monthly Net Credit Line money. It wasn’t signed correctly, they never received prove of my insurance after it had been faxed to them. I then set a letter signed receipt requested with prove of my insurance, then when I called, they Saud they had already taken over $3000.00 dollars out if my line of credit. After two months of on the phone, a supervisor agreed that they had taken the money out and yes, they had received my prove of insurance. I asked when they would return it. He had to check, one month later, they put $300 in my credit line. I called and complained so they agreed to return $700.00. Now they no longer give me ANY money in my line of credit. I called today and asked for a supervisor, as usual, put on hold and then hang up. I think I need to file a complaint with TX HUD as I believe that who over sees reverse mortgage. Nothing like taking advantage of the elderly. Sheila Carter
