Bad service

I have been pushed around from pillar to post when I tried to find out why the incorrect package of 2 Gigs was loaded onto my simcard for my Huawei mobile pocket device. I was expecting the 15gigs at R99. I was told to get another simcard RICA'd which I did then I was told that there was one waiting for me at DSV then nobody knew what was happening. I was told that I would receive an emergency parcel from DSV this morning at 11h30..DSV knows nothing about it. Please help me to get what is owed to me. Thanking you. Annelise
