Bad services !!!

My husband suspend the simcard about a month ago for personal reasons. When he came back from Mokopane he go to Vredenburg to get a new card and also sim swop. We paid the amount for sim swop and also the new simcard. They said we must wait for 3 to 4 working days, Nothing!!!!! We phone Vredenburg, but they dont pick up, we phone the *** number spoke with lost of agents, everyday they said today or wait for 24 hours. Then they said we must activate the card by this number, ***. We must pay R1330 for a contract but no activation. I spoke to a Megan the ref nr ***. When my husband want to cancel the contract they said we must pay R5000.00. We are very unhappy with MTN. Now I must wait today again for another 24 hours for activation. I spoke more than R500 out on MTN, still no help
