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.
