Is this $30k you're talking about a credit line? Or is the account actually $30k in the black? If the latter, you should have no problem getting credit to pay off RC assuming you aren't swimming in liabilities. In the worst of 2009 the company I work for was close to flatlining. It wasn't that we had experienced crippling losses (although we were hurting), it was that we were having trouble with cash flow. The boss actually loaned the business $35k to keep the business running. Gutzy move, but it paid off considering this year is going to be our best year ever. However, he didn't wait until we were unable to pay payroll and HST accounts or even A/P, although that would be the first thing I'd try to stretch.
Let me just say, without malicious intent, that you had a responsibility as the owner to make these payments or pursue steps to ensure your liabilities are fulfilled. You've missed deadlines and there are consequences for that. Although you still have options, you would have had much more had you not let it get so bad to begin with. Perhaps you should have considered bankruptcy? Maybe you should have looked for an alternative credit line? Maybe you should have looked at the sale of under-used assets, or cost savings? Maybe you looked into all of that and we just aren't aware.
RC is just trying to collect what is rightfully theres. You can't expect them to throw you a bone, although they still might. Does what you owe exceed $30k? How long overdue are your payments? All this is relevant information that you didn't give in your original post.
