Wrong statement proved for 4 weeks

I have given all my details on 4 differ days requesting a simple statement for a pure save account I opened and I’ve been waiting more than 4 weeks for the info. Today the 5-02-2018 I will sit in the branch until I have my statement. I arrived at the branch just after 2pm and I’m still waiting. I will wait in the building and sleep here until I get my information that I’ve been charged for each time I was told.
