Appalling and rude service from FedEx

The facts speak for themselves. According to the tracking info provided on the web page, my parcel (addressed to my wife) arrived in my home town of East London on the 18th Jan. On the 22nd Jan, desperate to find out why the parcel has not been delivered, I attempted to contact the East London FedEx depot using all four of the phone numbers that appear on various web pages, including FedEx's own web page for East London. None worked. Concerned, I decided to drive the thirty km to the depot to find out why they did not answer their phones. I must add the customer services link provided on the web page was of no help at all. At the depot we were told the parcel was in the hands of a courier and would be delivered to our address after 16:00 today (23rd Jan - five days after the parcel arrived in East London). It is now 18:45 and no one has contacted me to explain why the delivery has been delayed. Sadly, the staff at the East London depot did not respond well to my attempts to explain to them that they should investigate why the phone numbers did not work and were told that this was a head office problem and not their concern. Attempts to explain that this was surely a matter they should take seriously resulted in the comment that I was 'shouting' at them, a fact I strongly deny. As it was oblivious they did not take out concern seriously, I walked out, a very annoyed and dissatisfied customer. So my advice is, if you wish to make use of an efficient polite courier service, then don't use FedEx who obviously consider themselves too big to be troubled about the concerns of an individual.
