Cartrack - Appalling customer service

I am beyond all levels of frustration now, it is now almost a month that I have been messed around by Cartrack with regards to a refund where I paid the same debit order three times..

I am so sick and tired of hearing excuses from Cartrack – everyone is always on lunch, on leave or not available. I would hate to know what would happen in an emergency. I HAVE NEVER EXPERIENCED SUCH APPALLING CUSTOMER SERVICE – IT ACTUALLY DOESN’T EXIST!!!! Beyond all levels of frustration – I expect someone senior with integrity to call me.
