No response to emails and no device delivered

I have not received the device I ordered despite being told it would only take 5-7 working days from 9 March (it is a whole month later). I emailed them on 17 March, 23 March and 31 March to follow up and still no response to any of my emails. According to Telkom, my query has been resolved ... it is very strange that they consider no delivery of the device I ordered and no response to any of my correspondence as resolved. It is strange that one department has my correct contact number - the one used by the sales team to complete my order; but apparently other departments have tried contacting me on a different number. I am using hellopeter because it is the only way that i seem to get a response. I want this \completed order\" cancelled or voided or whatever has to be done so that I dont have to deal with this any longer."
