Horrible service, horrible communication

I ordered from temu on the 25 th of Nov 2024 I had been gettIng updates the usual way- pay import tax, wharehouse packing, in transit to airport, on the flight, arrived in SA, customs clearance and then finally- collection at airport on its way to courrier (Buffalo) this is when things get strange, as I waited more than a week and still not out for delivery- then suddenly when I tracked the order it said abnormality detected- I then tried contacting them on Whatsapp/ their email and their number and this was a struggle as all their operations are AI powered- Eventually after another week I contacted them and got to talk to an person- he explained that the shipment never arrived on the shipping container (this is strange because how did I pay customs on a missing package as well as all the updates) the guy explained that I will have to ask temu for a refund and that I would need to follow their refund procedures for refund shipping tax, I then got in contact with temu but this also was a tiring experience as temu still was receiving updates from the courrier company that the package is at the wharehouse and will deliver soon. After many messages to temu and a week later they refunded me this was just after Christmas, I then contacted the courrier company how to get my shipping tax back and they rep**** a few days later that they only accept a pfd version of the payment and that I need to fill out their forms. These forms are not attached to the email and i have rep**** requesting these forms but also no reply. Their service is horrible and I also cannot trace my package updates as now the system is reflecting that the order never existed so I don’t even have any proof- also how do they expect me to get a proof of payment pdf from the bank if I paid import tax more than a month ago.
