Called my cell. Left no message. Called back on another phone using "star" 67 first before calling them back 20 minutes later so they didn't get my number, it rang once and then nothing, no sound. If they picked up, they didn't say anything, I said (in case they had picked up) don't ever call me again. It didn't matter it wasn't on the same phone, it was just good to say it to whoever was making this annoying call!
