Does Buffalo International Logistics exist?

I ordered carpet tiles from Temu and got messages and proforma invoices from Buffalo International Logistics about 2 out of 3 packages(***..R53.68 & 8QHVHR..R67.56) for the import duty and VATthat I must pay. The order was divided into 3 packages. I am now trying to get info about the third package from Buffalo but with no success. I sent them emails and contacted them via Whatsapp and got only feedback from my W/app attempt, where I got the choice to chat to an agent, but so far no success, also the option to email them on "***". I did email them with all the details, supported with some screenshots, but no response from them. I got their bank details, they are with Nedbank. I had my doubts about them, so I went to our local branch of Nedbank to find out if this account is legit. The Nedbank attendant said that they are part of "Mustang" and that the account is legit. I tried to phone them this morning and got through to a switchboard where I had to listen to "Bridge over troubled waters" for more than 5 minutes, so I disconnected and gave it up for a bad job. What to do further I do not know. Shall I pay them the two amounts and see what happens? Or must I wait for a few days? I wish I can supply the screenshots to you but I do not know how. Kobus Bender.
