Metro by T-Mobile review: employee

I opened an account yesterday for my husband and the employee signed me up for insurance and put me in a different plan without my consent and without offering me insurance. I was a manager in Sprint for 10 years and I would terminate this employee immediately as this is unethical and not being truthful to her customers. She was also taking personal calls while assisting me. I am very upset and I want my overpayment reversed immediately
