The worst decision we ever made was to use Capital Visas. Our first caseworker never returned calls and then left suddenly and all the documents we had scanned and emailed to him were lost. We were given incorrect and conflicting advice by the case workers. It took them 6 attempts to get the online application form right - they kept sending us old versions that we had previously amended. My husband turned up at his first interview with a TB certificate that was not correct. The regulations had changed several months before and all the caseworker could say was "that's amazing". Capital Visas had also supplied my husband with the wrong form, an application to get married instead of one for people that are already married. At least 3 different people at Capital Visas had looked at the TB certificate beforehand and I had been assured that everythign had been properly reviewed. My husband's visa was not surprisingly refused due to a minor issue that could have been put right if Capital Visas had only done their job in the first place had they properly reviewed all the information we had given them several times. Capital Visas apologise but never accept any responsibility even for their staff giving incorrect information and they will not give us a refund. They will never give you the name of any of their directors if you have a complaint.
