Very poor customer service

after paying off both my store card and credit card I had with the retailer, I asked for both accounts to be closed to which I was given email address to sent proof of payment to for accounts to closed. I send email to both addresses I was given but for some reason they kept bouncing back and I decided to go the the same store I made payments in Horizonview shopping centre Roodepoort to get help for both accounts to be closed but to my amu*****t I was denied service until I present my proof of ID. What annoyed me is that I requested the account to be closed in the same store a week before and a lady manager mentioned that she remember me but their procedure require me to produce proof of ID irrespective. I’m angry at woolworths as a retailer because I’m being denied an opportunity to be debt free. Do I need to stress the fact that I was bombarded with phone calls where my verification was done without me showing anyone proof of ID, what is different this time around when the only thing I want is to be Woolworths debt free by confirming closure of accounts. This one fits all approach whilst hiding behind “security reasons”, must be done away with
