How do you guys compose your emails?
Make it short and direct. State the issue or problem you have. Long winded confusing stories are not needed. No one cares how many generations your family has shopped here it detracts from the real issue.
Managers at stores have employees to watch over, any customer issue that arises in the store, other issues such as if anything is broken and needs to be fixed they need to get someone to fix etc. They also have corporate calls or meetings with their bosses, going over promotions, issues, number crunching and whatnot.
Email is great, because if you just call, and they are busy you get angry while on hold or whatnot, or they need to contact you back later, more often than not you guys will be playing phone tag.
Allow 24-48 hours for a reply back on emails. Stores are open like everyday of the week, but that does not mean the manager works everyday of the week. That would be crazy, they have days off too. You may have caught them on their day off, mass emails just make you look like a crazy person. And every retail store has their share of crazy people who they've deemed better to ignore and will sacrifice your business to avoid dealing with you.
Another reason for a 24-48 hour delay between emails is because, they may need to contact another person. In this scenario, since the store manager on jermyn street does not work at the factory, He has no idea what is happening. He gets your complaint, contacts the factory, waits for a response before contacting you back. His contact person may take a day to get back to him.
While they are workers for a certain company, they are people too. People for the most part do not like confrontation, nor having to be yelled at. People who have issues but are still friendly and civil about it, are likely to be on the top of the to do list, those who are irate and angry you put off as long as you can. who knows, maybe they'll go away.
