Fedex Express disappointment

Appalling service from FedEx express. I've been getting emails from FedEx express for delivery of my parcel and expected to pay the delivery fee. First of all their tracking number is not recognised by their app. Secondly you get an error when trying to pay on their website but money gets taken from your account. Thirdly all there contact centre numbers do not work. Fourthly they don't respond to emails. With all this effort put into getting my parcel, I still can't get any help from FedEx. It's over a month struggling with this and am wondering if I'm ever going to get my parcel. My last option is to get in touch with the store I bought from to let them know of the service received from FedEx express and hopefully they'll be able to opt for another better courier company. Even the SA post office has a working contact centre number. How bad do you need to be to be beaten by SAPO. That's shocking service and frustration.
