Absolutely ********** Service

I have been struggling for a week to get them to send me my invoices for the past year as I need to submit this for sars efiling. I cannot download them off of their website as they moved to a new server so I have to go through customer care who keeps escalating. first agent said 24 - 48 hours and now its been a week. When I asked for a supervisor or manager to assist me they said they are not allowed to do that. The service is absolutely shocking and non existent!
