It was true that staff did inform us about the rule, but the question is why the staff did not prevent us from applying the visa. Instead they ensured that our visa would be valid and continue proceeding the process.
Indeed, I can understand that the service of IVS application centre is incomparable to other centres of developed countries; for example, VFS global.
However, as we paid for the service, we considered this as an unacceptable and ignorant action to customers due to lack of professionalism and responsibility.
We really appreciate your service. Thank you for being very helpful
