Account still not credited after more than a month

Placed my order Order # *** on 7 December 2015. Received an incomplete order, way after the turnaround time and the courier lady told me she was on leave when she delivered. Edgars apologised for the incomplete order and promised to credit the account with the outstanding items. To date that has still not happened. I have phoned Edgars more that 3times and have been promised that the issue is being escalated or its in the queue. It would be nice if the same effort that is put in sending us emails with promotions or reminding us when payment is due, is put in ensuring that errors are corrected and transactions processed in the month they occurred.
