The money cannot come from a friend. You need to have sufficient funds to sustain you in your own right for the period of time you have requested. My wife (Thai) has never been asked for multiple months of statements although she has a 9 year history of tourist visas. You probably should have sought advice first before submitting as now that you have an Immigration record you will really have to make sure you have everything in order. Do not appeal - resubmit but after seeking assistance (refer wrussell post).
Best of luck!!!
