Appalling Service

I brought my MacBook in for repairs at the Rosebank branch, paid the service fee before hand. They sent me a quotation on Friday the 4th, I rejected it and asked for the unit to be sent back, the email was sent before end of their business day around 4pm. They advised I sent the email after hours. I waited for Monday, where I sent communication at 8, I still have no response to 6 hours later. I went back to the Branch, and waited for hours on end, they told me I’d get the unit back before end of business, I asked for a letter stating that, I’ve been waiting for a hour now, for them to type the ****en letter. My experience has been horrific with iStore as of recent days.
