They will not stop phoning me!!

I took out a loan with Bruma Finance last year and am still paying it off, which is all fine and good.<br> They will not stop calling me to make another loan! They have called me multiple times, called my work, called my mother they have sent me emails and text messages! I have logged complaints, I have sent emails, I have told them over and over again to stop calling me when they do! They just keep harassing me over and over again!!! I know their number by heart by now and I want to change my number that is how bad it has gotten!<br> Very, very poor!!<br> When I tell them to stop they just say ok and then call me again,<br> I do not know how to handle this!
