We called Mr. Ahmed on Dec 29th, not expecting anyone to be available for the holiday (It's the saturday before New Year's Eve...). However, we arrived that same afternoon and began the first treatment the next day.
My roommates and I were sleep deprived and our nerves were frayed, but Mr. Waheed was reassuring and kind. He also responded very quickly to our questions via email and/or phone.
Pesticon was professional, punctual, reassuring, accomodating, and effective. We had our second treatment, and it's been about a month or so since we discovered bed bugs at our place and had our treatment.
Ironically I hope to never deal with Mr. Ahmed again because his treatment was so effective! Highly recommended.
