Dischem Athol Oaklands Blubird products tempered with.

I bought Biogen Ultra Mass 4kg at Athol Oaklands Blubird and one of the pack was opened. I normally buy this product and both the packs are sealed but this one it looks like somebody cut it open with a scissor. I even took pictures. When I sent an email to their complaints department, I get an error message that my email can’t be sent at this time.
