Reactivation - customer number

I had my customer number blocked because I hadn't used it for a while. I went back to the store in Butterworth 3 weeks ago asking for my number to reactivated. 3 weeks later my money is still locked up, no updates unless I call and the best answer I get is that people will follow up. I have gone and started the works I wanted to do with alternative funds and my things have come to a halt yet I have money sitting with cashbuild for no reason.
