I tend to agree here, customers are not always right. Most of the time they are wrong. If you look at the majority of SC support requests they a trivial things that could be have been learned from reading the documentation ( I know i'm guilty of this and have definitely pissed of support before with requests, however, I have also had a lot of suggestions implemented). But, again, you are paying $20 odd dollars per month for a package as a whole that offers far more value than any other trading software package on the market.
Most popular trading software( Ninja trader, TOS, TS etc) has a big network of vendors who try fleece traders into purchasing add on/ custom coded products. With SC there are hardly any 'indicator vendors" because if something becomes popular enough SC will development their own custom version and provide native support, and then usually charge nothing more for it. Users then point out bugs/ make suggestions and improvements which SC implement- There are pages & pages of support discussions that illiterate this. For example, the Number bars study( Footprint charts), Market profile/ Volume profile, VWAP & Dev bands, Jigsaw style trading Dom, Market depth historical chart- heat map( similar to Book map), Study summary window( similar to the TS radar screen). When SC develop their own native studies they will provide the source cdoe, and add functions so that the studies are accessible via ACSIL, so you end being able to fully customize a study to suit your needs. This is above and beyond what anyone else will offer you for $20 odd dollars per month.
If you want the kind of friendly support/ customer is always right attitude then you should expect to be paying $100 + per month. Investor RT is a good comparison of this( their base package is around $50, but with the adds on to match SC you will be spending well over $100).
You could argue that their customer service has become worse, but I'm sorry there is just no way you can say that SC used to be very good, and is not anymore. The current SC platform is far superior to ever before! It's not even up for debate. If you are having trouble with other platforms as well, then have you considered that the problem could actually be you?
....Ironically, I happen to be from New Zealand

But I have no affiliation with SC, apart from using their platform for the last 5 years.
