Contents of boxes received ****** and replaced with *******!

I have received an order of which 2 boxes was opened and the contents in it removed and replaced with junk. I am have a suspicion that I have not received all my boxes that they marked as delivered. Not first issue I have with Courier guy - also always receiving messages with links claiming I owe R15,00 etc for delivery which is impossible as parcel delivery payment is not my concern.
