Another corporate *******

I received an SMS 1st Dec 'You have 1 free month remaining on your T&B bonus 3 GB data...after which you will be billed R171.74 p.m. To opt out dial *135*140#. Popped into Vodacom to be told it was in my new phone contract. Clever, I'd only skimmed the document, certainly didn't see that! Tried the *135 number, doesn't work. 'Not available, non response number.' Even cleverer! Took time and effort, screaming at a robot, finally speaking to a human to cancel. I reckon 1000s of people have been caught and are spending R171 pm unknowingly
