Lack of Communication

After weeks of issues (at other Telkom stores) I finally got my phone sent in for repairs (by Telkom Express Brooklyn) I was really happy at first, but this soon changed as I had to wait weeks, and then finally phone myself to ascertain the status of my repair. Turns out that they had gotten my email wrong and had sent out a request for payment to the wrong person. Having **** what was due, I then again had to wait and received no actual response to my email asking for an update. At long last, I received a text saying the phone would be delivered to Telkom Express Brooklyn - this is where my real complaint starts. I have no way of getting in touch with the store to ask if my phone has arrived, the numbers listed on the telkom website and the mall directory go unanswered - and I tried multiple times. I also cannot find any email address to mail the store and ask. At this stage I am at wits end - what more can I as a consumer do to get information that should be shared whit me upfront?
