Delaying to replace bank card

On February 2015 I went to Jabulani Mall FNB Branch to downgrade my Cheque card to saving account. They gave me temporary card and told me it will be ready after seven working days. I went to check my card at the end of March they told me that its not yet ready and they gave another temporary card which is already expired. Im sick and tired of this temp cards because they sent me sms today notifying me that temporary card its about to expire please make sure that your FNB chip card is activated.my problem is I don't have one im still waiting for them to issue me the card. This service is not acceptable.
