Mtn do not look after their customers

My number was **********ly ported from mtn to cellc. After making a few phonecalls between the 2 networks, the ******* porting was reversed and my number was re-activated on mtn. As a result of the ********** porting, I lost my BIS as well as airtime. When I called the mtn customer care, I was told that they could not assist me as my number was ported to cellc.<br> I cannot understand how mtn refuses to re-activate my BIS when they can clearly see that I was a victim of ***** as a result of their failed systems which cannot protect their customers. They too are adding to the ***** committed against me because they should also be able to see on their network when I activated my BIS.<br> Extremely disappointed!
