Worst service ever at Edgars - from Stores to Customer Care help line.

I have an account with Edgars for Years. I never had any problems with the account in all my years I have the account. BUT I received my account this month with Interest I have to pay and also I bought something on 20M budget. Who on earth buys Facial products on 20 M budget account. I never ever bought on budget in my life and also do not want to ever pay interest. I tried to phone Edgars customer care line this morning to complain. Just to hold on for 30 min and nobody even answered the phone. What type of business is this? They ***** the customers money by wasting their time to keep holding on the phone, the customer must pay for the call and then they claim interest on something I did not approve. Who is going to assist the customers of Edgars??? The service in the Edgars stores is pathetic! Staff is chatting so loud to each other, ignore the customers and is rude when you ask for service. Actually, I do not know why they are employed?? They cost the company money!
