COMPLAINT TO MTN

I app**** for contract through mtn and i was declined due to my previoys account with mtn that was handed over to legal and that is new to me. I have ensured that my contract with mtn was cancelled after contract ended bearing in mind FOR THE past 5 years i have bought 2 properties and i have a record OF MTN my itc. And b4 you hand over the account you have to contact the client and NO ONE FROM MTN CALLED ME. I SENT AN EMAIL TO LEGAL DEPARTMENT ON MONDAY TILL NOW I HAVE NOT RECEIVED ANY FEEDBACK. IS THIS HOW YOU TREAT YOUR CLIENTS????? PLS NOTE I AM VERY INFORMED AND I KNOW PROCESS WHEN ONE HAS TO CANCEL ANY CONTRACT. I NEED YOU GUYS TO UPDATE YOUR SYSTEM AND STOP ROBBING PEOPLE. YOU MUST TREAT CUSTOMER FAIR.
