Temu frustration

As mentioned previously, I had 5 successful transactions with Temu. I realized afterwards that Buffalo was the courier company. Then afterwards Temu changed the courier company to Laser without informing me, which operated differently to Buffalo. Laser sent me sms's without showing their name in the sms's, thinking it was Buffalo. I responded thinking it was Buffalo to please send me an email with the link for D&T payment. I never got any feed back after several messages. Temu has refunded me the full amount for the returned goods. I will give Temu a break until Temu sort out their customer/supplier relationship.
