Complaint no follow up

Last month I wrote a review about how Buffalo International charged me extra to have a parcel from TEMU delivered, claiming wrongly, that the driver had called me. Buffalo rep**** the next day that someone would contact me and based on that fast reply I gave them 2 stars. However, it has been over 3 weeks since they rep**** and no call or email. I assume it was a bot that rep**** Hello Peter and I must change my rating to one star. I wish TEMU would change couriers as there are now thousands of complaints about Buffalo.
