Undermining and Discourtesy

I went in the store on the 19th May around 5pm and wanted to know what why my ring was taken so long to come back or get feed back from them and wanted to know my current options, That when the area manager Swash walked out from the back, barged in to my civil conversation with the lady who was assisting me, She raised her voice at me in front of other customers and went on to tell me about the warehouse and concluded with she's got no control over it I then asked why you telling me about tings you have no control off, and with a very discourteous and undermining tone she told the lady \Just credit that thousand and something rand ring!"and stormed out the store. Honestly if she was male and had spoken to me like that"
