Cell C customer UN-service

<p>I lost a cell phone on the London Underground. I need the cell SIM number to get it back from lost property. I have sent four emails in four days to Cell C asking for the SIM number. All I have got back is an auto-response saying that "We have received your email and one of our consultants will contact you within 24-48 hours". I tried an expensive 10 min overseas call to customer service and got cut-off twice. I desperately need this number to claim my phone (no ********** 429) back before returning to SA. CELL-C, PLEASE REPLY.</p>
