Rude mtn employees

Thanks for your speedy reply, basically I purchased a tablet A 7'inch, because of no stock I received the device 2 days later. The same evening once I got home I noticed the device was defective and wasn't charging plus the screen had a light fade on the left top corner, the Monday I called the consultant and informed him and he advised to come to the store as I have 7 days obf, I was unable to, so I took the device in today which was 2 days after receiving, as a result of me having a little car trouble having to change the Tyre so I put the box in the glove box not realizing my hands had a little black dust on it so the box got a little dirty. On arriving at the store I informed the consultant named Ronell of my situation and she immediately told me that it was against Mtn policy to receive the device because the box had been ever so slightly dirty. After making me feel extremely out of place she called the consultant that death with me initially as he was off and he informed her that it was fine. She then told me that I should keep the device till Friday because Mtn has no stock and that I had to wait because her manager wasn't there. I then proceeded to inform her that it was unacceptable that I take the device and that I'd rather cancel because bottom line it is not fault of mine. And if I waited that my 7 day period would of passed I then took her name and informed her that I will be laying a complaint. She then told me that she does not care and that I can to as high as I like a complain. This is truly unacceptable and unfortunate behavior because as a customer I have rights. Secondly I have 6 lines with mtn. I have never missed a premium and I have been a loyal customer and I don't believe that this is the manner in which I should be treated, she then continues to make remarks to the extent that I felt like I was being chased out of the store. Because of this experience I feel like canceling all my contracts with mtn and going to another provider. There is only 1 person in that store that gives good customer service and his name is petrous. I have been to many stores and I hate the bluff store because of the way the stuff make u feel. They really need customer service training because mtn is going to lose a lot of good customers because of individuals like Ronell......
