@parisba Lead with 10 year experience of customer service here. Did those guys denied you escalation? For real? The "it's not going to do anything" excuse sounds like they do not want you to escalate.- Keep calling (phone is much preferable). It hurts their one call resolution scores and a big fish at the customer experience team will eventually have to barge in.- File a complaint with any applicable regulatory agency or business bureau. Both tell them you are going to do so AND do so.- The nuclear option given the value of your losses, consider hiring an attorney to send them a proper warning
