VFS Global's online courier payment service is a mess.

My payments through two different credit cards as well as a debit card were processed successfully---the amounts show up on my card statements---but VFS claims that the transaction is not successful and will not allow me to proceed. I understand that technical glitches can happen. However, the worst thing about VFG Global is their complete lack of support. Their web pages do not list contact numbers or even email addresses. Eventually, I called the UK government (https://www.gov.uk/contact-ukvi.../y/outside-the-uk/english), paid 1.37 GBP per minute to speak to them, and got a support email address for VFS global ********** VFS's support really needs to improve.
