MTN DIRECT

On the 3rd of March I called MTN Direct to do an upgrade on one of my numbers ; a week later and its been a struggle between MTN AND DSV to get my parcel delivered to me ; excuse on excuse. The number I have been upgraded is in use with my husband ; and they would not take any delivery address from him ; so he is giving them my number "my other MTN contract number and the second time it needs to be confirm before any action ; after they told me its been added. really a customer for almost 10 years getting this service? MTN can cancel my contracts I will not pay them a sent again! and not even do they give you the 20 or 30 GB like they say with the upgrade!!!
