worst service ever

I cant believe that they were once the best providers but lately they are the worst. They don't give clear guidance, they billed me 3 times for packages I don't want. I only wanted to upgrade my line to a bigger line. they guided me to a new package which I did not want I only wanted to upgrade, they told me twice they will cancel the the incorrect order and wont send it out but yet nothing was cancelled, they don't sort out the issues. they are definitely not the best anymore. When contacting support they don't answer and when calling they just transfer you don't solve the issue and still expects us to pay
