Straight Talk complaint: They gave my husband’s phone number to someone else, TWICE

My husband has been with straight talk for over 3 years. About a month ago, I couldn’t reach him on his phone. As soon as I got home, he let me know his phone wasn’t working. When we called straight talk with my phone, they told him that his phone number was transferred to another phone carrier. She then let him know that if he wanted his phone number back, he would have to wait 48 hours so they could file a swap with the other company which doesn’t make sense because they just randomly gave his phone number away. After 30 minutes of miscommunication we decided to just change his phone number. Fast forward only 3 weeks later and today, they deactivated his phone again! I called customer service and was on the phone for about 20 minutes and got the same answers as before. Then the representative let me know he was going to investigate and put me on hold. I stayed on hold for over 20 minutes and finally hung up. This is absolutely unacceptable. He now has a phone plan with another carrier. We will never use straight talk again.
