Worst service ever with GFS express

Worst courier company ever. My parcel is still stuck on their watehouse in JHB since 18 October. Called more than 10 times. Am taken from post to pillar. They even accused another courier company whereas they still have my parcel. One rude consultant told me that they will return my parcel to Temu.... why, when there has not been an attempt to deliver it to me. Temu should stop using this company or they will lose customers.
