Credo Mobile Sprint Terrible Service and Deceptive Sales Practices San Francisco, CA Nationwide

I have been a long time customer, and starting in Oct 2014 I began experiencing major phone problems.  I was constantly receiving texts that said "no content".  I repeatedly called and spent hours trying to get the issue resolved.  They basically just talk in circles and no solutions worked.  I asked for a phone replacement and they refused.  I went to the BBB and then they offered to let me out of the contract but ONLY IF I returned the phones we purchased without any reimbursement to me for them.  They just keep sending the same response back to the BBB and are essentially selling a phone with unlimited texting that apparently has very limited texting.  I want to get the word out so other people know!
