Let me explain, If I entered the forum and asked "Is it normal for my service to drop at regular intervals even though tech support says it all looks good on their end?"
Let me explain. The title of your original post was Is poor customer service normal. Me reply to that was: No. Actually, I should've clarified, that customer sertvice is not poor at all, though sometimes, due to external circumstances such as a worldwide pandemic, it may be slower than normal and perhaps not meet our expectations as customers.
Is that helpful or constructive? Does that contribute in a single useful way to the situation?
It is helpful and it provides an answer to the question in the title of your OP.
There was no reason to chime in and then he persisted.
This is a customer-to-customer site, and customers will chime in. And typically, when the OP is willing to work things out with his/her fellow subscribers, there is progress, and many times there are solutions.
