Worst customer service ever!

I have after 22 years of being a Edgars customer and I have been a very good customer decided to close the book on Edgars, there service is non excitant, Being in retail myself I understand how important customer service is but I believe because Edgars don't value there customers they believe that 1 unhappy customer is not important ,but the lesson in Retail is the customer pays your salary. I have had to FICA my Edgars account since last year October , I did it 6 times and when I phone Edgars customer service I get the attitude : I don't know and its not my problem, if its not the one thing its the other thing, Thus after 22 years I decided to close the book, I will pay my account off and close the account, I lost out in discounts alone R3500 on my Edgars account this is just unacceptable - no apology no compensation, All the do is harass you for payment , I have decided that I will treat Edgars like they treat there customers - really so disappointing after being a customer for so long . The worst is my surname and my name is spelled wrong and after correcting and asking please change this , it' s still wrong - Edgars must realize there are other retail stores!
