MTN no service Caller Line Identity

<p>I have been a client of MTN for over 20 years. On Sunday 2nd July I went to MTN Baywest Mall and instead of renewing my contract I opted to go month to month until the new Samsung Note is released in October. After they moved my contract onto the month to month option I no longer had CLI on my phone which has proven to be catastrophic for my business as I have a counseling practice and if a client phones me and I miss the call I do not know who has phoned as all calls now come up as "Unknown". I have spent countless hours at MTN Baywest and countless hours with MTN call centre trying to sort this out without any success. I have even resorted to placing a complaint on MTN South Africa's FB page and sending them a message to no avail. Shame on MTN! Such a huge corporate company and they can't sort out a simple matter like CLI on a cellphone. How do I sort this matter out as I feel I no longer have any options having gone direcly to the local MTN dealer, the MTN national call centre and gone onto MTN's FB page? Is there anybody out there?</p>
