Can the Dept of Aging assist with a over-payment problem with Social Security retirement benefit?

My husband is an American. He moved with me to Canada two years ago and started collecting his social security at that time. He was 62. My husband commenced working in Canada and was working part time at 84 hours a month. My husband was careful not to exceed the income limit that applies to recipients under full retirement age. My husband was conversing with Social Security in September and he was asked about his employment and additionally how many hours he worked in a month. He advised them it was 84. They then informed him that since he lived out the of the country that he is limited to 44 hours in a month. My husband was unaware of this. Prior to leaving the USA for Canada he had a stroke and his attention to details since has been clearly lacking. They advised my husband that he would owe for any months that his hours exceeded 44. My husband did not gain a lot of income from this job - he made more from social security. Since then they have cut off his social security. We sent in the information they requested in early October but have not heard from them since. I am now sharing my job with my husband so that his hours do not exceed 44 in a month and we have advised Social Security of this. We have been without his social security for 3 months now. We are living on his small income from our part time job as well as a very small pension that I receive. Is there anyone who could help us with this problem. There are definitely mitigating circumstances at play with this situation. Any help would be appreciated!
