This is the American Kidney Foundation, according to a Google search of caller ID. They will come by and pick up clothing, household items, small appliances, furniture, etc. - even things that they may be able clean and/or repair - to sell at a thrift store type place in Charlotte to raise funds for their foundation. I spoke with them months ago and got a number to call whenever I have something to donate. Saves my having to drive smaller things to a thrift store myself and good for those things that I can't fit into my car. Seems my number has been put back into rotation. They stopped calling me for a good while after I got the # to call them and also asked them not to use my # anymore.
