They Sell Your Cell No for SPAM

<p>I recently purchased rims for 2 tyres & on completing the purchase I was asked for my cell no.</p> <p> </p> <p>Since then I've been getting more than 2 sms' a day from car related companies trying to sell me stuff.</p> <p> </p> <p>I never authorized them to use or sell my number. This is ******* use of client information!</p>
