POOR CUSTOMER SERVICE

TNT Johannesburg branch received my parcel on 08 April fro China, I have not received my parcel up until no, they don't phone and give me the feedback I have to phone every time to give follow up, they asked me to send invoice from the vendor, I did send through , they said I must pay R783 for customs , I paid R850, but still I did not receive my parcel , the guy with name Derel Naidoo asked me to send my Bank Statement he was loughing at me he said they will charge me more money , I asked him for what and he say for customs but I already paid R850 , how can I buy something for $60 and Shippment for $65 + packaging for $ 35 + South African Customs for R783 and still have to pay more ????? I believe TNT IS *****ING FROM PEOPLE., now they want my credit card bank statement . I am very angry and I need advice from you
