This is the problem and a lot of people don't have the knowledge to know, they don't require it
Ever been to Currys and they try to upsell you on the laptop, TV, vacuum cleaner etc? If you don't tell them specifically what you want they will look to sell you whatever their management are currently pushing (either to max profit or to get rid of old stock). And of course when you buy that TV they will tell you that you will need a new HDMI cable for £50.
Not for many years have I been to Currys, the last white goods I got, which was the Freezer I got from a local company, Vacuum cleaner from Amazon, TV from Argos, online, they do try and sell you some insurance, but doing it online means just ignore it.
i know they do try to upsell things, certainly PC world that used to try and sell more powerful machines than what the person needed. The last time I got anything from Currys was my Huawei phone a few years ago, I went in, told them what I wanted and told them not to try and sell me anything else, in and out in 10 minutes.
oh yeah, the HDMI cables with gold connections, to make the ones stand up better and the Zeros rounder. As I said, I got my last Tv from Argos and ordered it online.
Or when you buy a pair of shoes and they try to sell you the shoe protection and cleaning gubbins.
Not had that for years, but then again I order my shoes online from Shoe zone and then pick them up
Or when you are in a restaurant and they will try to push the specials or convince you to have a desert (the waiting staff are their as much to try and increase the take per customer as they are to serve you the food - a higher income per customer means better profit for the restaurant).
I don't do restaurants, I pop into a cafe now and again, but restaurants is not me.
All of these and many more are examples of up selling. Every industry does it to maximise their profits. I am not surprised that ISPs do the same - income per customer is a critical number and the higher it is the better your bottom line generally looks.
The difference is they don't keep trying to upsell, you're on a broadband service, and they have your email address, and they can keep pushing. Thankfully most do have a leave me alone tick box in the contact preferences and most do follow that, apart from Talk Talk.
Plusnet contacted me twice to do with selling me stuff, one was their TV service, but I told them I don't have a Tv licence and the other was to do with their mobile phone service. No point in contacting me about updating my broadband, as I was on the fastest speed I could get. They did contact me when my contracts were coming to the end.
Zzoomm, been very good, they sent me emails when they were doing maintenance and when we had that bit of a problem when someone decided to cut the fibre at the start of my time with them, but that was it until my contract came up for renewal, and they were even late contacting me about that
i thought they would have sent me emails asking me about going to a faster speed, but they have not.
