MTN STAY AWAY FROM 24 HOUR MOBILITY

I am have been reaped off by the company that associate itself with MTN. I am begging MTN to look into the dealings of 24 Hr mobility before they loose many customers. I am leaving MTN any time soon cause I can not operate with this company I need my devices to be insured but not with 24 Hr Mobility. I claimed for my 1Phone 5 they told me my number has last been used on that device couple of months of cause I had upgraded to an 1 Phone 5s as a result iPhone 5 I had to use it as a secondary phone which I had to put another sim card. Few months I cancelled another tablet device but they kept on deducting the premiums when I asked them they promised they would refund me until today I am still waiting. They do not care about MTN customers they only care about the premiums they deduct from us as clients. I am done I was going to upgrade to a MacBook but sorry I have requested the settling amount from MTN and moving as far away from this 24 Hr Mobility and MTN. If MTN cared about its customers they would have looked into these cases as I am not the only one that has been reaped off by this company. I have paying premiums with MTN fro years over R600 and over R400 with 24 Hr.
