Pathetic Service from Edgars

I have been calling Edgars so many times for them to assist me with my query. They send me to in-store, then in-store sends me back to the call centre, yet my query has been unresolved for over 4 months. All I wanted was for them to sort my payment plan. I have requested over and over (close on the 15 times for a higher Manager to call me, yet till today no Manager has contacted me. I have spoken to the RCS collections people as well, yet people tell me all they can do is write notes on their system. I have numerous times requested a Senior Manager to also call me and no one bothers. I have previously made a complaint on Hello Peter, yet to date no one from Edgars called me. Once I settle this account I will be permanently closing my account and will no longer purchase from Edgars in future.
