Because there is no reason for a company to call me unless it’s urgent, at that point it is perfectly fine to call.
Some companies call regardless of the reasons with no care at all about the customer, all just to make sure to force a response. Just send the damn message instead and If I have any sort interest, opionion, 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.
