Zero rating, if that were possible

If I could give this company a zero rating, I would. Absolutely ********** customer service. No one answers calls. They take weeks to deliver packages when the companies you purchase from offers delivery no later than 7 days. No communication with clients regarding delays. When you call, if they actually answer, all you get are excuses. I have no idea how this company has managed to be around for so long and why big retailers are still using their services.
