Heavenly promises that directed me to hell

I have requested to cancel my warranty, which was debited earlier than it should have, from an account that had no funds, and therefore incurred bank charges. im still been given the back and forth regarding my refund. You get promised heaven and earth when you buy, and get forgotten after that. no one wants to assist. Im dealing with a Nthabiseng Mpila, whom I send emails on a daily, and she just does not respond, or tells me she has escalated my issue, but have not gotten feedback since. Does she even read my emails and action, or does she just ignore? Only she knows.. Poor service indeed. very disappointing.
