BAD SERVICE

Friday the 24 i went to mtn here at mutual park pinelands to buy a charger and was assisted by a black lady forgot her name. She then asked the type of a charge I'm using I told her is a C type she asked if I'm buying whole charger on cable i said infect let me buy a cable only because i still have the charger its only the cable damaged. she gave me a cable and i paid and left. when i got home the cable was C type on both sides meaning that im unable to connect it to a charge / adopter. put it back in a box and kept the slip. today went back to mtn to return it and luckily same lady was there so i told her she gave me wrong cable she refused to admit she made a mistake she told me that i should have said i want the old cable not the new one. My question to her was when you ask me i told you i have the adopter so how were you expecting me to connect this cable to adopter she fought and told her she is now wasting my time I'm on tea i want the correct cable , i was told to come back during lunch cos manager is in a meeting. i told her i am not going to do that wasted my tea break there and now my lunch again because of her negligence because she is the one working for MTN she was suppose to explain to me that there are 2 types of cables . she just gave me correct cable and change with out an apology nothing and was left feeling disappointed with that kind of service when i then realized that i do not have a slip what if this cable doesn't work i went back and ask she didn't even look at me and she told me i told you to come back manager is in the meeting. Guys this is not the type of service we expecting when we go to the stores we use our own money to buy products i am very upset and disappointed with the service. ***
