Sick and tired of Homechoice calls

I am sick and tired of receiving marketing calls from Homechoice. I spoke to one of their telemarketers and informed her that I do not require an account from them and that the only reason they have my number is because I made a cash purchase from one of their stores, so I provided my cellphone number so that they can contact me to collect my order when it has arrived (how I regret doing that), so I humbly requested the lady to remove my number from their call list but instead I have been bombarded with special offers and even a personal loan by Homechoice. I have blocked several of their phone numbers from my cellphone but they continue to call me with different numbers. I am usually not rude to telemarketers, but I am about to lose my cool and make an exception.
