how do I opt out of auto renew messages

How can I opt out of "your account will auto renew" text messages from Smarty. I don't want every organisation I deal with sending me expected messages over and over again.l

@JohnBra_2967681 @Turn off auto-renew? The message acknowledges that they are going to take money and this is quite common with many companies in these days of high fraud levels

Telling me they are taking £5, wow!

@JohnBra_2967681  I don't think it's about the amount, more the fact that they are taking your money.
