When you come across a what you think to be a Company from Hell and your back is against the wall you will often feel isolated and alone, more so if you have a look around at some of the business review sites and you note that the excellent/good reviews out weigh the bad reviews by a long way. This can often add to your insecurity, well actually this can be turned into a positive, more so if you realise that many of poorer quality suppliers actually pay professional to write reviews and post them with 5 Stars or high ratings.
The Write a Review industry is massive and growing all the time and these professional will charge anything from £9.00/Review, they can even post multiple reviews for a single company using different IP and E-mail Addresses. So in a nutshell I would take what you read on Review Sites with a pinch of salt.
If I have a problem with a company my starting place for more realistic reports are Consumer Forums and then search for the company by name some worth a mention in the UK are: -
