Saftey of customers not their concern

I was waiting for the price of the item to be corrected. Scanned wrong. No apology from supervisor and no double the difference. In the mean time my phone was been ******. I have been in contact with head office and all I get is it has been escalated. Pathetic service and lack of customer saftey. I want my voucher to the value I had to pay the ****s to get my phone back. My kidz are hungry!!!!
