Yes! The situation is serious and must be corrected as soon as possible...

You have no control: one negative review posted tomorrow can tarnish your reputation.

Put yourself for a few moments in a potential customer’s shoes. To make his choice, he has no reference or reviews on you. Whereas if on your competitors’ side, reviews were filed, particularly if they are positive, the balance will tip in their favour...

Without realizing it, you may miss on many customers. Therefore you must solicit feedback from your customers and publish systematically on all available media.

Otherwise, adverse effects could be similar to too many negative opinions (and even more devastating!).
