WHACK DSMAL service, being overcharged on basic while apparently i should be on plus

I have been in a struggle with this company, since 2022, issue started when i changed my insurance and ive been struggling with feedback from them as customer service is non existent. I was on the nestar plus when was using my previous insurance,, the minute i switched, they moved me to a basic one, i sent countless emails in 2022, and was told that is the correct one, i stopped complaining, now come December i decide i want to move to netstar plus, now they tell me im already on the plus, how is that when i dont have the access to the features that are part of the netstar plus. Will i get my refund since they have clearly been overcharging me for almost 2 years now? Now ive sent countless emails and no one is responding, I HOPE YOU LOSE CUSTOMERS BECAUSE OF YOUR BAD SERVICE!!! I'm almost at the end of my contract, cant wait to cancel this ****
