Fedex keeps you in the dark

I order a package from Alibaba that was shipped on the 14th of February tracking number ********** 20651. I got a call from Glen Molambo on the 17th to pre clear the package, made the payment for customs and duties and at this stage everything was running smooth and my worries about all the negative reviews on Fedex started to dissipate. Until the 20th when I got a call from Rudy Subaya telling me my package was randomly selected by Customs for inspection,she asked for my email adress, (this by the way is the 5th person asking for my email adress at Fedex) and told me the email will give me details as to what was required, I asked her just to clarify the situation, she kept quiet and put the phone down in my ear. I phoned back before they could ran away from the phone, but all I got is "the email explains everything" something a robot can also tell me. I sent the documents the email requested and tried to follow up the issue with Rudy to check if the paperwork from my side was in order to ensure no more delays, because speaking to the call center is useless, when you phone the call center they give you each a different reason as to why it is held up at customs, I phoned 5 times got 5 theories. The call center did however give me the managers cellphone number Sanjeev Lutchman 081 723****and the switchboard at Fedex Import department ********** 777. NOBODY and I mean NOBODY Picks up their phone not the manager not the SWITCHBOARD it rings till it dies 10 or 20 times I tried. Rudy just send me a STENCIL email at the end of the day comfirming receipt of papers I emailed. I can understand that customs are doing their jobs. But fedex is not. There is no one that gives you the idea they REMOTELY give a flying f about you and your packages that you paid lots of money for. No communication,nobody at their phone and I mean NOBODY not the manager with his cellphone in hand not switchboard and this is in business hours. Fedex keeps you in the dark,up and till now I dont even know if the documents I sent in was suffiecnt. Fedex lives up to its bad reviews.
