No customer service and apparently no experience in clearing parcels with discounts

UPS South Africa doesn't have the capacity to deliver on the service they sell.

A 3 days service is now more than 3 weeks, parcel again held by customs. It is the first time I used UPS for these parcels, since it was to be an express with pre-clearance. I have imported many parcels fro the supplier through DHL and NEVER experienced this type of NON service I got now with UPS.

More than a week ago I was told to supply proof of a discount I got from the supplier., which I did with confirmation from the supplier. Today again, I am requested to get the supplier to prove the discount with "other" customers!! FFS Why could UPS not handle this properly? Apparently I am "the first" client with a discount problem they see!!!! The incompetence in the clearing service just mind blowing. I have spent hours on the phone trying to get hold of people to try and assist in resolving this, yet didn'y help.

I will NEVER again use UPS. I will go back with standard DHL seems.
