Three questions kill most of the confidence in a thread like this: sample size, blinding, who paid.

How do you get a clear photo of an imprint? Mine keep coming out blurry. Not on a pink oval tablet but the pattern is familiar.

Filing early beats arguing later. And ask for the reference number, always. Same for me with a scanned-as-delivered parcel, unfortunately.

I would stop trying to convey how bad it is and start saying what you want them to do. Not on a random thought but the pattern is familiar.
