Terrible service from Maria Fransic at MR Price

I went in one of the mr price stores to return some items that I bought online. The staff and I were trying to figure why I can't get a cash refund when one of the managers said that shes going to call head office to find out properly. Anyway she called the head office/ call centre and then came back to tell me to speak to the consultant over the phone (Maria Francis)

The line was really bad becasue the stores phone wasn't in the best of conditions. So i asked the consultant to please speak up as I couldn't hear her clearly. The lady went frantic and in an aggressive and rude tone told me that if she speaks any louder she'll be screaming. I was so scared at that moment to carry on speaking to Maria, I felt extremely uncomfortable & anxious (as I tend to get anxiety attacks). As all i requested was for her to speak up she really didn't need to be so arrogant. I completely understand if i was rude to her, but i really wasn't.

Before i ended the call I think she realized the panic in my voice and quickly changed her abrupt tone, but at this point i felt really uneasy so I decided just to take down her name so that I could report her.

What if the next time she does something like this to someone and they maybe have a hearing disability? Its extremely important for consultants to be tought phone manners.

Worst mr price experience ever!!!
