Mr Price continues harrasment

I have been inundated with marketing calls from Mr. Price. I keep on asking that my contact details be removed from the list and have emailed the customer care. After I've blocked the calls on my cellphone they have the audacity to phone me at work. I don't understand how many more times I must request not be contacted.

My details are on Direct Marketing SA not to be contacted as well. I'm not sure if the Mr. Price group is part of DMASA.

I'm very happy to close my account if that is what it will take to stop the harassment.
