OId Mutual very unprofessional

On the 4h of Jan 2019 I logged into Old Mutual websecure site to do some financial transactions by moving funds around (fund swithces )to get the most benefit from share prices. Unfortunately when I logged in, this site was no longer working and I was directed to a new site. As I was not told about this new site and handed some guidance I went into the site and battled to find out how to request fund switches. I logged a query on the website AND send mails to listed mail addresses to find out why this site was changed without our knowledge as well as how I can request a switch. 3 days later - without a reply, I managed to figure out how to do the request online. I have already lost out on the 3 days delay as the funds prices did not move favorably to me in the 3 days . I have send a couple of mails after that as I still have some question about the site and I still need to know why it was changed without letting the members know. All I got now - after 3 weeks, was a mail with a form to complete a switch but still no answer to any of my questions. If I had not figured out how to do the switch online I would still have been waiting for the switch to happen and I would have made significant losses. I am not happy with this at all. Old Mutual decided to change their website without advising us and when the queries come they are not prepared to assist. If I was not forced to invest in my employer retirement fund with Old Mutual I would surly have moved somewhere else.
