Refusal of Service by Senior Staff Member of Woolworths store in ForestHill Centurion

I was shocked by the lack of service I received from a senior manager in woolworths for that matter. I visited their Foresthill store in Centurion, Pretoria where staff uses their on discretion without consulting policies and procedure in paper yet have a nerve to tell me as a customer "I know too much" from a manager in charge name Octavia. I went to the store to return and exchange some items that they assisted me but I now feel that I need woolworths to take back and give me my money back as the treatment I got no longer makes me feel they value their customers and I should go elsewhere. the manager refused to print me a policy where it states that a Debit card has to be produced to be seen by cashier to process refund further more she made me wait and said she will look for it while i saw her just sitting at the table where the computer wasn't even on, where further she turned me into fool because she could have used the computer at the cashiers which was on and policies are there this was advised to me by my friend whom I was with and she was recently working for woolworths that is how she knows this. The senior manager looked at me and said she will not print for me the policy because I am talking too loud and other customers can here me i asked her to tell me what abuse or wrongful language did I use to apologies because i knew that I was telling her facts and the truth that as a manager she must know where the policies are and not tell me I am going to wait hours and hours... she further answered that she will not give me service after I asked her if she wont and i am not sure if woolworths retail allows this that a customer can be told that they must turn away no service will be offered to them without any abuse of language but an ************ of challenging them to do their job right and produce the right documented policies and procedures. today is the last day to return a sale item for full refund and i have since written a complaint online and not yet received any contact back. I want my money and top of it all I wasted my petrol because of driving there to be refused service by an *********** Manager which is even worse!
