Delivery

I normally buy weave online, when I do so I don't get any kind of invoice from the seller what I receive is an sms notification. My seller is using FedEx, this is my 3rd order and I have never been asked to provide proof or anything either than to pay an amount to customs. I placed the order on the 10th Nov, 15Nov I called FedEx trying to track my parcel. I was told the parcel is with customs. I called again 17Nov, I was told the same thing by Judy whom I spoke with Friday 17th she said since its late Friday she doesn't think I will receive the order she will make sure she gives some kind of feedback by Monday 20th. I did receive an email Monday from Judy requesting an invoice. I then sent an email to China to the seller, he sent an invoice which I immediately sent through to FEDEX after that I received an email saying the invoice is incorrect. I then called FedEx spoke with Innocentia who said the reason they are disputing the invoice it is because the amount on the invoice is too low $15 and the hair inside looks expensive than the price on the invoice. I explained why. Reason being the seller owes me $35 on my previous order, on the current order he had to amend the price that is why I ended up paying $15. I even sent the conversations between me and the seller regarding the discount. She then suggested to get a statement from the bank for the transaction. I called the bank Monday and today I was told my statement closes on the 5th of each month and the transaction will only be available after the 5th of Dec. I then convey the news to Innocentia with the contact number for the bank but I haven't heard anything from her. That was the first time people from FedEx contact me about my parcel. I called again the next day 21st Nov. a consultant I spoke with told me to get an importers code from SARS, that very same day I received an email from Judy with a sample of an invoice. I sent a request to the seller requesting a second invoice. I sent that invoice yesterday afternoon. I have heard nothing from FEDEX till now.
