Letsatsi Finance stop harassing me

Can someone please tell the agents at Letsatsi Finance that I'm not interested in any of their products? I receive countless calls from them everyday, its like I'm being stalked. I block their numbers after each call but they always manage to call me with a new number everyday. I'm tired of being harassed by these people. Please guys remove my number from your contact list. I don't even know where you got my numbers from. I hope this will solve my problem. I'm not happy at all. PLEASE LETSATSI FINANCE, LEAVE ME ALONE. I DON'T NEED YOUR PRODUCTS OR SERVICES!
