Urgh... One of the worst things, when you want to contact someone and they have hidden every means of doing so. It reflects badly on the companies that do this and questions why such pages exist to begin with. I understand why companies hate spam, but when a company hides customer service, that should be a major red flag and reeks of cowardice. Customers can and do have major problems, not just Karen type issues, but being ripped off for hundreds or even thousands. They sometimes hide behind underpaid staff who are students or can barely speak English.
It's all dependent entirely on scale. If a bajillion customers have major problems (whether actually major or in their mind), you have to triage and the first tier won't be experts with excellent command of English. Support is fucking expensive. Everyone wants bespoke service, but if you are not a customer, or if the amount of business you bring does not justify the expense, the support level you want cannot be provided in the long run.
Yes but that's a bajillion dollars you could, instead, pocket.
Walmart seems to have no problem staffing their stores with employees who can answer questions, among other things. And they actually sell real hard goods, in meat space.
Scale is a lame excuse. Yes your labor will have to scale with your customer base, that's just how a business works. That's a good thing, actually, because that's how we keep society from crumbling.
Yes, Faecebook is one of the worst. I hate companies that blether on about community guidelines but refuse to say how you violated them. (Which in some cases may be an error.)
