Retrenched- Account blocked. Employed can't get account unblocked. USELESS

Got retrenched and my insurance paid my account however I have notified Edgars and their insurance company RCS that I am employed and I am paying my account but few months later and my account is still blocked. Tried calling but I was sent from pillar to post. Get transferred to insurance department as they have to unblock the account and the line gets cut (multiple times). Tried phoning the direct line to the insurance but a voice operated system tells you to phone customer care, again. Customer care tells you to phone insurance. Then went into store to find out the customer service desks have been closed down as there is a new system. Just to find out the new system is that the instore staff has to hold up the entire line at the till points to follow the same process I have followed from calling and emailing customer service to the insurance department and dealing with the same useless non helpful service.

Needless to say my account is still blocked while I'm paying my account due to Edgars RCS having poor systems and the worst customer service.
