Unhappy client PEP Store Park Meadows

i am writing to voice out my grievance about the service i received from the Pep Store in Park meadows Eastgate from the ill mannered manager Thando Msese. I walk in the store looking for a memory card and there was no one attending to the cellphone counter where the memory cards where placed and i then asked for her assistance not even aware that shes the manager, she then came over to assist and i asked about the memory card pricing and why it was priced in that manner because there was a pricing list but the list was about a different brand so to say and she then with attitude answered and said they all priced the same way,i then further enquired but she insisted that's just how the pricing is...as I walked away with my colleague i commented saying to my colleague i don't understand why is it that they priced the same way even though the one on the pricing list is more advanced so to say i mean i work in the cellphone industry so i have a clue here and there. Thando the manager said in turn even though i was no longer speaking to her said "then you will understand" and i turned to question her about that statement and she swung her hands in my face aggressively saying "you will understand sisi(in Vocab),I got upset and asked as to who and where i escalate this awful service i was faced with she arrogantly said Im the manager!, if this is how PEP treats their customers i am appalled and a very unhappy dissatisfied client. Please correct this kind of behaviour from your employees especially management!
