Visa rejected - applied after 11 July

Hello everyone,

I applied for visa on 25 July and I got rejection. I am worried and need help, so please reply with suggestions.

My visa rejected on the basis that there was no continuous business activity before 11 July. Probably we made a mistake and we presented a contract which was dated after 11 July. Our business account was opened after 11 July.

However we send advertisements and business website which was before 11 july (does this not come in business activity? ) also we sent self employed invoices dates before 11 July (does this not come under business activity?) and our business was registered on 20 June 2014. We have appeal rights.

Please suggest what should I do?
Many thanks,

File appeal
