MTN IS USELESS - DUAL SIM PHONES

I have been with MTN for over 20 years. In the past I had only good experiences and therefore it PAINS me to report that I will switch from MTN to Cell C. WHY? On ALL their phones they DO provide a DUAL SIM as ADVERTISED by the manufacturers of the phones. In the meantime I will use my old CELL C phone WITH a DUAL SIM to conduct my business and private needs. Your phone is USELESS TO ME AND I WILL GIVE IT TO A FOUR YEAR OLD TO PLAY WITH. This is how much I value your services........ USELESS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
