I don't understand why others are having problems with Correctional Billing Services. I set up account to receive calls from my son. First you have to find out what billing service to use from the jail to set up a phone account with so you know you are going through the right company, and you may or may not get your money back depending on what company you use. You must read their terms and conditions. When my son left Harris County, I had $97.00 left on the account so I called to get a refund from Correctional Billing Services and I received my refund check within 6 weeks. No problem! Harris County did not offer electronic mail to inmates so no problem. I sent him letters. If you have problems with a phone representative, ask for another or hang up and call again later to get someone else. Some of those foreign people don't know what they are doing. Some companies don't take time to train well so the employees learn as they go, and sometimes you just can't understand with their accent what they are saying. Be patient and believe things will work out for you. :) There is power in positive thinking. My son is in Montgomery County now so I had to change phone service company to Global Tel Link for that jail, and I don't think they issue refunds so I put the least amount on there. All is cool! :) When he goes to TDC, I will have to find what phone service they use. It's a chore, but I do it for the love of my son.
