Core Resource Management

We invested $25,000 Into a IRA Debenture Bond to this company. They guaranteed 7 % interest paid quarterly on the 15th of the month following each quarter. It is now 8/3/15, 3 weeks late & we've not received a check.That has been Core's common practice in spite of their original promise. They originally tried to get us to convert the interest checks into their stock at $2.00 per share. We declined. The stock sells for forty one cents per share in the recent markets.I call the company & leave a message on their recording & get no returned calls. We are both 76 yrs old & can use the money. We'd like for Core to keep their promises.
