BAD AFTER SALES!!!

I really think the service @ Vodashop Malmesbury isn't up to standard. I've upgrade my phone 19 February 2015 and on 22 February 2015 I've noticed that the charger isn't working. I returned the phone on 23 February 2015 within the 7 day period. On 2 March 2015 I still didn't heard anything from Vodashop Malmesbury. I returned to the shop on 2 March 2015 for feedback. Feedback: phone need to be replaced, but they don't have any stock. That was the 2nd of March 2015. Today it's the 9th of March 2015 and I'm still without my Lumia 830. How long do you have to wait for a replacement? Please Note, VodaShop Malmesbury's ***) after sales service is pathetic. Stay Away!!!!
