My 70 year old mother who knows nothing about text messaging showed me her phone the other day. On it was a bunch of messages from 654654. So we reviewed her bill and found that she had been paying $9.99 a month for Predicto service. Upon calling Verizon, they told us how to cancel the service and they promptly credited the amount. They also put a block on premium content.
I the text messagining world, Predicto is refered to as a short code content provider. There are lots of different content providers. Then there are the Aggregators. The aggregators bundle together blocks of content and make it available for telelphone companies for use on their networks. In this case, Predicto Mobile's aggregator is a company called Open Market. Ultimately, carrier's such as ATT or Verizon are responsible approving or dissapproving content campaigns for use on their networks. If too many complaints come in for a particular campaign, then a carrier might drop the content because they don't want the headaches associated with custmer service.
There is a standards body that sits over the short code ndustry. It is called the MMA or Mobile Marketing Association. The MMA sets up rules and guidlines such as the double opt in. In my mothers case, she never opted in at all. Somehow she got slammed.
The rep at Predicto told me after taking te mobile nuber that my mom had double opted in on a particular date and that she had record of confirmation from Verizon. When I asked for a copy of the record, she claimed to have never said there was a record. They put a lot of fancy talk around it. The double opt is simply a text msg sent to them. Most carriers don't carry text message records that show destination... His means that your case is not easy to prove.
Predicto should be ashamed of themselves. I don't know how they are still operating.
