Paying my customs tax for SHEIN clothes however Buffalo refuses to send my parcels despite sending numerous proof of payment. Buffalo team is heartless struuuuu

I bought clothes from SHEIN early March hoping to get them last week of March, i did payment and got confirmation of payment, on the 21st i got a SMS from Buffalo to pay customs so I can get my parcel, I did. As i was paying, there was a system glitch between banks and SHEIN, i tried doing payments which i was not successful, i was doing payment from my Capitec bank, i then used my FNB card to pay as i was frustrated. i tried and the same thing happened, only to find out i paid twice from Capitec and three times from FNB, this was the beginning of my struggle. Buffalo team made sure that i struggle big time, they moved me from pillar to post, their system would not accept the proof of payment despite my explanation, the consultants are very rude and not friendly. .
