PLEASE STOPPP

i don't even know where to start. i settle my Lewis account more than a year ago and when they called me therafter, i told them to close the account and remove my name as i don't want to take any thing. to my suprice they called my 3times a week and even on a sunday in the morning. i spoke to numerous people and eventually ask to speak to the Manager. she promised that my number and name will be taken off as it takes 7days to remove. 2 weeks thereafter, someone called me again telling me i have credit available. i told him i don't want and want my name to be removed, spoke to manager or assistant manager and she promise they will take my name off. afetr a month i got another call from Lewis Athlone branch, again i told them to stop calling me and remove my name as i don't want there credit and will lay a complaint should they call me again. Today they called my again telling me i have R36000 credit.. I'M SO SICK AND TIRED OF THESE CALLS AND I HAVE NO ****EN IDEA HOW TO MAKE THEM STOP CALLING ME. HOW DIFFICULT CAN IT BE TO REMOVE A DAMN NAME AND NUMBER FROM YOUR SYSTEM. Are you that desperate for client that does not want your credit. STOP CALLING ME AND REMOVE MY NAME OR ELSE
