Complaint Ignored

I logged a complaint with WW customer service on 12/09/15 regarding the lack of feedback I was promised to have received the same day. To date I have not received any response. I emailed again and received the response that \I do not have access to assist you". I find this unacceptable especially since I was promised feedback on 12/09/15. The nature of my complaint was the fact that the \""department\"" who is able to assist in unblocking me from applying for a store card do not work on a saturday and I was expected to call back on Monday. I do not have an account with them but was advised that due to an invitation I was blocked from applying. That means nothing to me and should not even be my concern. Their systems should be accommodating and not even have an online application on a saturday if they cannot assist customers until monday. It is highly unacceptable. The call centre agent was rude and blasphemed"
