Irresponsible hooligans

I took out a contract with Vodacom, Mall of Africa but their sim cards never worked for full 8 days. I returned the phones to the store and they took them back. They are supposed to refund me my R210 for sim connection that never even happened. When I took the phones back, they checked and confirmed with me that everything was in there as it should be. 4 days later when I decide to follow up with them since no one cared to call me back as promised, they tell me that they can't refund me because there were no simcards in my phones. At first, they told me that they can't refund me because the sim-cards were already linked to the system and they can't use them again. Now they just called me saying they are only willing to refund me half the price. Why should I be punished for their negligence??? I want my money!!! I am not letting them go and I'll make sure that they pay for this.

When I left the store, Susan assured me that they will DEFINITELY refund me. Now they are finding loopholes not to refund me my hard earned money. There's a lot of dishonesty here. Pay me back my money!!!
