It is against the law to robo call/auto dial a cell phone. Call your carrier and let them know. It was enacted many years ago before the unlimited programs they offer now. I had 800 numbers from ATT.com call me every day even though I blocked everyone of them they used they were still able to leave a message. Which was some man with a foreign accent saying I had money on an account... disgusting. What was creepier was there is no phone number record of them calling you. Just me calling to retrieve the message. It took 3 months of reporting every time they called to file the compliant and calling my cell phone carrier. What's even worse is that 800 numbers are not listed and you are unable to find the company that it belongs to.
