It is the applicant's responsibility to ensure that the application form is duly filled and signed, application fee is paid, and (any) supporting documentary evidence(s) as required are submitted.
The ECO will make a decision based on the evidence(s) in front of him - and it is his/her discretion to believe the authenticity of your claim(s) or not to do so. Can you prove to the ECO that the original statements were presented to the VFS staff (and not just photocopies)? No matter how frustrating it may be, the bottom line is that such a claim is difficult to prove (if not impossible). From an ECO's perspective, it is the applicant's responsibility, not VAC staff's, to ensure that mandatory requirements are adhered to.
If the ECO decides to not overturn the earlier decision, it is not expected that you'll receive any communication on the matter from local BHC.
Appeals are time consuming and, IMHO, inappropriate to assume that a decision will be overturned by the ECO as a result of claims you have made ... unless you have provided evidence to support your claim(s).
It is known fact that appeals usually take 4-6 months (or more) to reach a decision, if the decision is not reversed by the ECO at local level. Local BHCs do not entertain status enquiries unless customer service standards have exceeded, and moreover, they cannot advise you on timelines when your appeal is to be / has been forwarded to FTTIAC. When the appeal is registered with FTTIAC, you can expect to receive a Notice of Pending Appeal (IA10) and the time delay between issuance and receipt depends on method of communication used.
To give you an idea, ECOs have 8 weeks to prepare the documents for sending the non-settlement appeal to FTTIAC, and AIUI, therefore has 8 weeks to decide whether he/she should overtunr the decision or not! For non-settlement appeals lodged at post the earliest time an appeal would be heard is, 16 weeks after the appeal was lodged.
If the delay is something that you cannot accept (for any reason), you may wish to withdraw the appeal and make a fresh application.
