Blatant incompetence and lack of service!

This is the worst service I received from any courier company in my entire existence. After sending them the necessary details (ID number, address etc.) and about seven phone calls to repeat the process at least three times, my parcel was returned twice to the country of origin, with a message 'parcel returned by buyer.' Eventually, the seller returned my money. In an environment where online shopping is at the order of the day, I personally think UPS can close their doors. The service wreaked of incompetence and just blatant lack of ANY form of customer support. In fact, I am in complete awe that any company with such poor customer service have survived for so long. I am speechless.
