I received text saying reply OK to 65488. this is a free message from mobijo, the 1st text came at 00.39am. I text Stop at 0040am.at 00.40 I got the same text as 1st one, then at 00.48am I got another one all saying same thing, I have just sent them another text saying Stop at 00.52am, they have just sent me another 2 texts at 00.53am saying the same thing. Reply OK to 65488. this is a free message from mobijo. how do I stop these as im not paying for any texts to them. is there a different number you have to use to stop these. please help. thank you.ive just had another one at 00.57am, this is absolutely crazy, they're obviously going to keep sending them until u say OK. they've got no chance, im phoning my mobile company so I don't get charges on my account.
