Bank of America Mortgage Complaint

Bank of America Mortgage department,

Home equity loan or line of credit Loan modification,collection,foreclosure Arizona

I have an line of credit with Bank Of America for $370000.00. I have never been late on any payment because they were charging me interest only. 3/4 months ago they told me my line of credit matured and now they will start billing me as 15 years principal & interest and they payment will be somewhere about $2700.00 a month. I explained to them there is no way I can make that payment as I have first mortgage and rent is only $2300.00 a month. I am already $2000.00 upside down. I asked them if they can differed the loan as for 1 more year so my first mortgage will be finish and I can make the payment after that. They told me they can do nothing and I do n't make enough money to refinance. No body told me about hardship application or anything only thing they said was best thing to do is put it on short sale. I have made payment when economy was down. I borrowed the money and I want to pay it back. I just need help till -/-/2017 when my first mortgage will be over and I can make regular payment to Bank Of america. Now since they ruin my credit I ca n't even go and get any refinancing done at all. Please look at my payment history I have made good on my loan all this time even when economy was really bad. I do n't want to ruin my credit and I do n't want that I did n't make good on my loan on my conscience. Please help me fix this issue. It seems people who were good all thru the bad economy are getting punish for being good.
