Edgars Call Centre staff not willing to assist and drop calls without resolving my query.

Very bad service received from the Edgars Call Centre on 07 May. Staff dont know what they are saying and are unwilling to help. Make clients hold not speaking, don't know how to accommodate a simple request of decreasing a credit limit. Previously they had an option on the call center prompts to do this now when you talk to staff they say you cannot decrease your credit limit. Ref number not able be given and name not provided. She dropped the call when i said she must give me a reference number when complaining so i can take the matter further.
