Bad customer service from Milady's at N1 City

Made a formal complaint to Milady's at head office on bad customer service and I was promised Feedback in the form of a call back from the store manager. I received no calls and when I enquired about the feedback, the lady said that the store manager tried to get hold of me via phone, however, I had no missed calls from Milady's. Then I was promised an email and to date no response. It's true what the reviews state about Milady's bad service to customers. I am strongly thinking of closing my account. This would purely be to prevent them from treating me like a ***** in the future. Cause they have no regrets.
