BAD SERVICE AT ADGERS

I went to edgars westgate shopping center. I wanted to close the account i have with them. The store assistant told me to pay off the balance which was R127. 62. After i paid he put me on the phone to call the call center. After holding almost a lifetime a lady answered. I gave her my ID number and told her i want to close the account. She said with confidence that she will help me do so. She requested my email address, cell number and home address. Which i gladly provided. After all that the girl told me i need to send them an email with all my details for a credit check before they can close my account. I told her i just gave all that information and she said it was correct now why must i send an email? I told her in the beginning of the call you said you will help me close my account and now why all this. She told me its procedure. I feel so angry and feel i was treated like a fool. Bad customer service really. She should have told me from the beginning that i need to send an email instead she made a fool of me by giving me an impression she was going to help me then tell me i need to send an email. Secondly i dont understand why they are doing a credit check when i just paid up the account and want to close it. I have proof for Gods sake. I know by tomorrow they will add anounts and expect me to pay. The service was bad and unfair to me as a castomer. I held the line for almost 20 minutes to be treated like a fool. Am not happy at all. Their service is bad. She did not even bother to provide the email address that i was supposed to send the email to
