NMG Benefits is just a mess

NMG being my pension fund administrators. I have been trying to get them reset my log in credentials for the past month or so in order to check how much I have in my pension fund. About six months ago they gave me the log in details. I changed it to my own and managed to log on once. Next time I tried to log I was told the credentials are invalid. I tried to call them but their phones are never answered. I sent them an email, I was told to supply them with my 🆔 number which I did but since then which was around the 20th of last month they have been just quiet. I sent them another email but Still no response, I'm literally so frustrated. I don't really know which part of this company is working: they never answered their phones, they rarely respond to our emails, their WhatsApp line is NOT working and also their online portal is not helpful. Is our monies safe? People..All I need is my log in credentials to be reset, the sooner the better. Is that too much to ask?
