Contract upgrades issues

I have app**** for a contract upgrade and the consultant send me the wrong contract. They already send me the phone, and then another consultant told me they need to pick up the phone. It has taken of 8 phone calls, numerous emails, talking to customer care but still nobody can give me any answers on what to do about my contact. I have tried every avenue and still every consultant says somebody will phone me back.

After 20 years this is the worst service I have ever received from a service provider.
