If you ever wanted to complain about a product or poor service would you prefer complaining in person or would you prefer to complain in writing. What could be the better option of the two? Each of them has its advantages: -
When a person complains in person, there is a chance that the things could be communicated in a better way. Sometimes improperly chosen words could take the matter the wrong way.
Complaining in person could convey an indirect message that you are not there for fighting but to get the issue resolved. This could be a more trusted thing todo rather than going forward and just complaining in writing.
While complaining in person has its own benefits it could mean there is no official document that represents your reaction to the bad product. In the court of law, proofs are required.
A person may forget if you complain in person. The matter could remain hanging for long and you might lose what you could gain with a proper complaint.
Complain in writing means there is something official.
The customer care service has been developing greatly with many of the bigger companies however at the small and medium enterprises level this is still not the same. Complaining in person is not easy always. Wherever this could be done, the option could be to complain in person first then go and complain in writing.
The point to be remembered is that the time difference between written and oral complains should not be too long to damage the case. Genuine person would help you at the first instance but there would be some who would only give promises.
While the above mentioned thing is good but for valuable products a written complaint would certainly help and if no personal communication is possible.
