****** item out of flyer bag while in The Couriers Guys care

I ordered hair from my supplier in JHB and they used The Courier Guy to deliver parcels. I had two parcels on the 11th from the supplier, the first parcel was delivered around 8:30am that parcel was sealed proper and all my items were in there. The 2nd parcel was delivered at 11:16am my parcel felt light for two wigs so i took a picture of how it was sealed because i know how my supplier sealed it, when i opened the parcel a wig was missing then i logged my query on the day with the Cape town hub. They did an internal investigation where they found another wig in JHB and i confirmed it was not mine. i provided the branch manager with the images of what was sent to me and how i received then she started another investigation where i was included on , one of the team members made a comment to say that "they don't think the d4river needs hair" of which i never said the driver needs hair i was piolet with my query and today after a week the Branch Manger informs me my query is closed after reinvestigating my query with no substantial feedback. and this is not the first time ordering from the supplier and the courier guy staff tried blaming the supplier or my mailing room department of which i confirmed to them that not the mailing department or my supplier stole my item there is footage and confirmation from both sides and they failed to provide me with their findings and i asked the cape town branch manager to call to discuss this issue but she never did but only answered my emails once a day.
