They've been very helpful in our registration with ICEGATE. It was a small thing with a small amount paid which somehow escalated to a very painful procedure. Never did they say "You've only paid so much. It's too much effort for us.".
Very pleased with their service. Prompt, professional and great communication. Definitely recommend. Special mention for Ms. Razia - she handled our case.
Professional Utilities is fully professional in their work, Rates are too low and genuine. Services and satisfaction are high so I highly recommended Professional Utilities.
They are one of the most genuine and reasonable people. I applied for lmpc certificate through them and they charged me a very nominal amount as compared to what other firms asked .
