HOMECHOICE HARASSING ME WITH CALLS

for the past 2 weeks, Homechoice has been calling me 5-7 TIMES a day asking me to place an order. i have no idea where they got my number and why they lie and say i made a request online. I asked one of the call centre agents to delete my number from their system as i'm not interested, this morning alone, i already have 5 missed calls from them. HOMECHOICE, PLEASE STOP CALLING MY NUMBER, THIS IS HARASSMENT NOW!!!!!
