RSAWEB extremely poor service

I bought a new laptop and, as a client of RSAWEB, they assisted me to set up Outlook and my email account using IMAP. After a few days I wished to re-set my emails using POP. On Friday 7th Sept, I spoke to Brandon on the support desk. I granted him access to my laptop, who, after an hour, advised me Outlook had been *******ed and I need to speak to an IT specialist to re-install. It was his mess and he must rectify the problem. I then spoke to Shanaya who managed to restore the files but my emails were still not working correctly. She became impatient and blamed me. I requested to speak to senior management but instead was put through to Kyle. I granted him access, and after almost another hour, he hadn't resolved the problem. I then suggested he needs to actually create an email account - which he did and problem solved. He undertook to call me Monday morning 10th Sept to check if everything is working. He hasn't called me and there are, in fact, still incorrect settings. The worst part is that senior management is inaccessible and I am being ignored . Besides my 2 verbal requests for senior management to call me, I have lodged 3 written requests on Tuesday 11th Sept at 10:55 am, 11:45 am and again today, each confirmed on RSAWEB reference 943861. This poor level of service is totally unacceptable
