If the reviews are short and not deeply mentioned then there are chances that the reviews are fake. Reviews should be locked with all the information with the actual data points like date of usage, product details, executive you have spoken to etc. Some reviews are outlined with very less information which is probably not the right review, purposely trying to affect the reputation of the business. Businesses check their past records to resolve the issues but if the reviews are less informational then there is no solution for these kinds of reviews, neither they will get resolved nor removed, they are just putting a mark on the brand reputation.
For eg. “Worst company ever”, “bad company” etc
