Yeah, because everyone is happy to wait 4 days to get the answer to a question about if something is in stock or something. Posted letters are a relic and should die alongside linear broadcast prerecorded television.
Imho this is the average time car parts suppliers take to respond to a similar email question.
We have this great invention for getting more immediate answers, called...the telephone. You enter someone else's number and they answer and you can speak to them and ask them right there and then...
Which leads me to another annoyance - people who will only reply by telephone, even to emails. Mostly because they don't want to leave a paper trail, if nothing is written down, they can promise the world and then "forget" about it.
Agreed. If I was wanting to speak to them I would have phoned them. But I think another reason is laziness, I may ask several questions in an email and it is easier FOR THEM to phone me rather than give a detailed written response.
