Extremely unhappy no progress with orders from Edgars online

Very unhappy with Edgars online deliveries, been waiting for progress with a order to be delivered and for 6 days/4working days it has not even been collected by Courier guy, when I have placed order that were delviered by Dawn Wing/DPD Laser I did not have these issues. Edgars customer care says they packaged and are waiting for Courier Guy to collect, while Courier Guy say that they have a backlog because Edgars wont give them the parcels. Edgars customer care says they can't change the courier company and I can not rate my satisfaction or dissatisfaction.
