RSC commit ***** on Edgars customers account

Since Edgars was taken over by RCS the accounts have gone horrible wrong You can't contact them because they don't answer there phones You send emails and still zero reply You go to Edgars branch they manage to get a consultant on the line which is hopeless trained A manager Mr Craig Binnedell will give you a call but 2 weeks has gone by with zero response.My problemis I had a account at Edgars for 40 years but suddenly RCS change the rules on the account without my permission or that I have signed any documents with RCS to do these changes which means they have done ***** on my account When you try to contact RCS they are missing in action because they hide behind the mysteroius wall
