Shiprocket — Fraud by courier service

I m very dissappointed with shiprockrt as my complaint was not taken seriously. and not investigated properly. my 2 pakets were changed and delivered to customer after changing inside content in sealed courier bag with changed shipping label. i complained about this and given all image proofs what i sent what buyer received, its clearly showing packets were changed and shipping label is also different

the support service excecutive saying its delivered in intact condition but there is no proofs for that. if it was in intact condition then how the shipping label is changed. i given all proofs, and images i clicked on the time of packing weight dimentions all imaged is on panel, but inspite that my compaint was not taken seriously. every time its denied saying its delivered in intact condition.
