Worst experience ever. They didn't show up without any notification. After that, I rearranged the pick-up date but they again suddenly cancelled my appointment on that day. They wasted my time and energy. They are not reliable. The manager didn't even express any apologies. Only explanation given was "due to high volume of deliveries." If so, they should have contacted me in advance or not confirmed the appointment. I don't recommend using their service if you find any alternative.
