Inside UK visa application no updates

Submitted my application on 25 May 2026, provided my document and biometrics on 15 June 2026, received an email from UKVI saying they received my application on 20 June 2026. Since then until now, no updates, no emails, no calls, what can I do? Check on visa processing time, it shows I should expect a reply on 10 August 2026, but none. Tried to call them, but only advisor picking up the call and ask me to keep on waiting. Tried to email to my local MP for help and submitted a complaint to UKVI, still waiting for response… but I need to travel back to my home country by the beginning of September for signing legal documents, without my visa approval I can’t travel… Really need some advise and help please…. 🙏
