False Advertising on Website

I just recently opened a account with FedEx, so on their website they say you will receive upto 45% and quite frankly the quotation I received is actually higher than the quote I received from my supplier who happen to be using FedEx as well, so clearly no discount there and even much higher fees so after I noticed this I thought maybe I’m not fami**** with the website I called to have someone assist me with requesting the shipment as stated in their website that if I opened an account with them which I did I will receive account management, when I called them today the First Lady I spoke to was Dimakatso she told me she couldn’t locate my account and that I needed to speak to the sales team, I held and ultimately I was hung up on. I don’t know what’s happening to my shipment request I have no idea if they are collecting it or not, i basically don’t know anything and whether this shipment is on my account if the account exists or if I have to make a payment on card I’m just literally clueless and this means I have no control over my shipment, quite disappointing
