CHAMPION SPAMMERS

I have never used Ramco Motors. However, I receive more than 3 SMS's per week from them. I have SMS'd STOP, I have called them and requested that they remove my number from their database. I have asked to speak to their MD - a Frank Ramos. He apparently only comes in to his business at month end. Every time I call, they ask me for my cell no and promise it will be removed from their database - to no avail. They told me I must phone from a landline, or my cell number is AUTOMATICALLY added to the system again - if this is true, it is *******! Calling a business is not consent to receive spam.
