Annoying calls!!!

Calls calls and more calls! It's becoming extremely annoying when they call every single day, sometimes 3 times a day. They call from a 082... or 079... number. I have been blocking these numbers for over a year now and they change on a daily basis. I work in a corporate environment and don't have time to answer these annoying calls. When you say you not interested, they still call you a few hours later. I don't usually complain but this is harassment. The lady I spoke to today advised that there is a problem with their system when it comes to closing a call. I settled my account just to get rid of the calls but that is not working. I have no faults with your quality of products but your interest rates are way to high. I will rather pay cash than buying on the account again. Homechoice please stop calling me!!!!!!!!!!!!!!!!
