Temu use couriers who are useless

I ordered a few items from Temu and the parcel was given to Speedaf (Meili Logistics), a different courier from the one they’ve used for my previous orders. A few days ago, I received an exorbitant bill for VAT & Duty Amount to be paid but proceeded to the payment point as I need my goods. I’ve now tried to pay that bill 4 times, but after my bank sends an SMS asking me to approve the payments, the transactions fail. I’ve spoken to my bank and they said that the problem comes from Speedaf. I’ve tried to contact both Temu (where I’ve only been able to interact with a useless Bot) and Speedaf, who provided me with a phone number to contact, but after well over 10 attempts over 3 days, nobody has ever answered my calls. They don’t respond to my emails of WhatsApp messages either.

It appears I’ll never receive my package, a real problem as I can’t buy those goods elsewhere. I also wonder whether I’ll ever get a refund. An order from Temu made a week earlier was delivered by a different courier and arrived promptly.

If Temu continue to use Speedaf, I won’t be able to buy from them again. It’s a pity as I have a long list of items which I was planning to buy in the future.
