UPS pathetic service levels

If you can then please refrain from using UPS for any importing/forwarding/clearing services. There's plenty more service providers who's service levels are 100 times better than theirs. I see that it is a common threat on the reviews that parcels are being imported where it arrives at UPS's Kempton Warehouse and then nothing gets actioned by them, they actually sit and wait for the customer to eventually contact them before they action anything. When you then follow up with them the service levels I've experienced are truly pathetic. I've now been told that I will have to wait 3 business days for them to confirm what the customs amount is that I need to pay for them to release my package after it's been lying in their customs warehouse for 2 weeks. I would also like to warn other businesses or corporates that uses clearing and forwarding agents to refrain from using UPS if you don't want to risk losing customers. From my knowledge there are more than enough good players in the industry so you don't have to settle for the worst out there
