Calling/Suspecting me of *****

The treatment I received today have never been so hurt and angry the staff suspected me of being a *********, I was purchasing a cellphone and then I received a call from my mom asking where I am she got a call from truworths telling her that they suspect a ***** purchase on her account yet I'm using my account not my mom's account I gave the lady( Genevieve) my ID and my bank statement and Khetiwe called my mom they called her twice about this so I asked the 3 ladies that were serving me and they clueless about this and the manager couldn't give me a straight answer about this she kept saying they don't know who phoned they will need to find out who made the call, I was questioned about my own account I even asked the guy from head office that phoned me that how come I get to be treated like this whereas some of the staff knows me and the guy that greeted me even asked where are my kids today as he knows me I usually come with them to buy and now with the cellphone purchase I'm suspected for ***** like really now truworths I make sure I pay for my account monthly, I will pay your account and close it thank you very much for your service. I have never been a ***** nor a ********* in my life. I don't see myself making any purchases in future thank you.
