Not happy with their service

I am not getting any help from Dionwired Greenstone <br> The item I purchased has a material defect <br> We bought 2 Samsung Galaxy Camera's from Dionwired Greenstone last year, the salesperson Stephen remembers us well. The one camera had a problem and was sent to Samsung for repairs, it was sent back to me, and still not working properly, I took it back to Samsung again. Upon this they discovered that the part they needed is no longer available, they told me to go back to the store to give them the paperwork re the part, and that Dionwired should give me another camera as it was still under warranty.<br> Unfortunately in the time we bought our cameras we were also in the process of moving and we can't find our purchase slip, I asked them to please look up the invoice, as I had serial, model numbers.<br> I was promised they would, but to no avail.<br> We have always been loyal clients of Dionwired, and have spent thousands at this establishment, therefor I find it not acceptable to be treated like this, Portia is ignoring my emails.<br> Stephen the salesman can confirm that he sold it to us, so what could the big problem be, this was a limited edition camera and that should not be an issue
