One of the most commonly faced problems, companies use the service and end up not paying, this is such a shameful situation, and this situation is alike with big and small companies.
I do agree , no matter how bad the response is, maintaining a professional image will always serve good in the long run.
I was wondering is there a common place where one can black list the companies, is there a website that maintains the black listed companies , it could be for various reason. If any one of you is aware of a website or forum where we could blacklist the defaulting companies, please let me know.
