Sorry no service on a Friday

How can a company of this magnitude not have any helpdesk personnel on a workday? When we moved from the previous administrators to Alexforbes they didn't load the beneficiary details correctly. (no beneficiary). Luckily I noticed this and wanted to correct it immediately. Firstly their online site don't allow me to update any personnel detail? Then I phoned only to find out they have NO (not one person) available to handle any queries. I got told to phone back on Monday. I obviously complained that this is not acceptable, what if I passed over the weekend, I need to get this corrected today. (after all, it's a working day....all their clients cannot suffer because they decided to train the entire business on the same day?) The 'helpful' receptionist then transferred me to a recording that told me to phone back on Monday, and then it ended the call automatically. I feel I actually might pass of high blood pressure before Monday!!
