For starters, I rented a portable wifi for 4 days. However, it arrived one day late. Furthermore, I had a tour planned and was leaving at 7am and back at night... Hence, 2 days lost with no wifi. THEN, I package the wifi and powerbank in one silver box as told and have my hotel ship it back. 3g contacts me and tells me the powerbank is missing and I am charged for it, and of course no refund for the 2 days, not even the ONE day in which they were late. Absolutely horrible customer service. I would rather have zero wifi for 2 weeks than go through this company again.
