SSDA is Pathetic / possibly **********

SSDA keeps on calling me via a cellphone number to say that my MTN contract has been handed over to them. I have contact MTN and on two different occasions MTN has stated that my contract is not handed over, and I have copied SSDA in all these emails as well, but they persist on calling me, but they never respond on the emails that are send to them. I have even asked that they sort it out with MTN as MTN has stated my account is not handed over, and my account is still active and not suspended. I keep telling SSDA this when they call, but they just call again the next day. So this problem is still not sorted out, and I am beginning to feel that there is something fishy going on. The ref SSDA gave me is **********. This has now been going on for a few weeks now. But SSDA always fails to respond on any emails sent to them. Nothing is getting sorted out, and the will be consequences is SSDA blacklists my ID, as I have the correspondence with MTN that i am not handed over. I want this sorted out and my name to be cleared.
