MTN, ARE ****MERS

Mtn has been ****ming me for over 2 years. I have been overcharged for the last 2 years. I have called mtn numerous times, i get a reference number, then nothing happens. I got to the Mtn store i get a ref number , then nothing happens. They just dont care. Now my contracts are expiring and they call me for an upgrade. What a joke of a company. Beware of these ****mers, They will lock u up to a contract , then overcharge you, and there is nothing you can do about it, I am done asking for a credit , as in a few months my contracts expire and i will be moving over to Vodacom. MTN , WORST EXPERIENCE EVER, STAY AWAY FROM THESE WHITE COLLAR ********S
