MTN Selling Second Hand Phones As New.

Now it's over a year and MTN hasn't resolved this SERIOUS issue. I been paying for a second hand Samsung S8 Plus which MTN sold me as NEW. MTN repairs faulty phones, re-packages the phones and sells these phones as new to unsuspecting customers. Phones will be boxed as new. This is what happens when you return a faulty phone to MTN, they send it for repair and box it as new and sell it without disclosing anything to customers. I am deeply HURT. Guys just know that receiving a boxed phone from MTN is no guarantee the phone is new. I found out the phone had been opened before as it had a service number manually written on the inside of the back cover. MTN l bought a new Samsung 8 plus from you and you delivered a second hand phone to me, l WANT WHAT I BOUGHT FROM YOU MTN WHICH IS A BRAND NEW PHONE NOT SECOND HAND PHONE. MONEY IS HARD TO COME BY MTN, YOU CAN'T DO THAT TO ME.
