Waiting for sim card, memory card and cover to be returned

On the 4th of October my tablet Dixon TS-M706E has been sent in for repairs at Cash Crusaders Adderly Street, Cape Town (Stock Code ********** 3). As they could not fix the tablet I received a new tablet on the 1st of November. However a MTN contract sim card and a memory card were still in the old, broken tablet and I didn't get the cover back. I was told that I would get the cards and cover back this week and I would receive a call when I can collect it. I didn’t receive a call and am still waiting to get the cards and cover back. As a sim swap and a new memory card costs money I either want the cards back or money to buy a new memory card and sim card. Please call me on ********** 211. Johannes Weber
