Poor customer service and ************

I been facing financial difficulties and went into the Gem Potchefstroom store to report and make payment arrangements. As per the consumer law. When I was referred to the cashier Claudia to explain and make an arrangement. Firstly she didn't even greet my or acknowledge me. She the started screaming and shouting at me infront of other customers. After the store manager remove me to discuss with me she discuss me with the following client. I received some of my payments and send someone to go make the payment and she refused to take the payment as if she's the store owner. It is with in my rights and I acted according to the consumer law therefore should the Claudia send anyone to remove my furniture from my house forceful I will lay a charge against her and the store and sue the store. I know my right and consumer law. She's acting on personal feels and would like to make a point in a wrong way.
