Well my opinion is that there is no reason for a company to call me unless it’s actually urgent and in my own best interest, at that point it is perfectly fine to call.

Some companies call regardless of the reasons with no care at all about the customer/client/potential customer, all just to make sure to force a response. Just send the damn message instead of disturbing me at work, and If I have any sort interest, opinion, or care what so ever, then I’ll get in touch at my own discretion.

Having customers isn’t a “right” for companies, but they do seem to believe so.
