Home loans make their problems mine

They migrated their system, losing information and then sent threatening SMS that the account was now not FICA compliant and would be frozen. We supied them with all the documentation as requested despite it being their mess up. We still are getting SMS's now again and have now had the account frozen despite having the reassurance that it was compliant. This despite many long (45 minute plus) phone calls at my expense, the time wasted in following up when no one replies to emails. And the aggravation. They caused this problem, they made it ours and now they are doing NOTHING about fixing it.
