Very difficult. They give you the run around. The first person telling you to go on line and email. Then if you do get a response it doesn't really pertain to the issue or they tell you to speak with the first person who told you to go online.
They kept me on hold 30 minutes plus, refused to escalate, everyone is in a meeting and they give you pat answers.
No. It is impossible. Someone answers the phone only to tell you that they will call you back because they are very busy attending other clients. If they call you back, it will be days later, not same day.
You have no chance, I tried for months, emailed, called, left messages, never got a response.
