Ignoring clients , making empty promises.

I have emailed the store owner on the 25th of August 2015, regarding items that was ******. I have purchased all my devices from Vodacom, all my accessories everything for the past 5 years and the insurance requested my receipts. I understand to try and get the receipts for all those years is to through a needle in a hay stack. They know me personally their as I worked their and know I have purchased all the items.I phoned them 3 times and emailed 4 times the just ignore me.I have even written the letter to simply it for them , all they needed to do is confirm that I have purchased the items from the store.I spoke to Goodwin who never came back to me , my emails was read but they didnt respond, I phoned again the manager said Niva the owner was in a meeting she will be out later they will get back to me. I have emailed numerous time still no feed back , this is really bad service. This is a very urgent matter and they just ignore you. In my days this would have never happened.
