No feedback/closure

I experienced a numerous amount of unauthorized purchase activity on my credit card on the 31/12/2014. After a few weeks I received credit for four out of the six transactions that had taken place that evening. I emailed Minzelle back to inform her that I had only been credited for 4/6 transactions. She responded with \ Herewith we confirm that the merchant processed the client towards your account. Kindly request more credits from the merchant ". I tried contacting her directly"
