Extremely disappointed

I am extremely disappointed with the customer service I have received—or rather, the lack thereof. Over the past three weeks, I have received no communication from the Hisense service department. After a technician came to inspect my washing machine (and provided subpar service), I’ve had no follow-up from Hisense. I’ve called the service department more than five times, speaking with team managers who make endless promises but never follow through. Is this really how Hisense treats its customers? This level of disrespect is unacceptable.
