No response to order

I app**** for an LTE Huawei modem online on 10 October. After completing and submitting the application, with all my personal details, no reference number was given and was notified that someone will contact me. No such call was received as yet. I have been to Telkom stores but they are unable to help me as they claim not to have access to the same system. I have also tried calling customer service and was given other numbers which operators never seem to answer. I would like to cancel my order but cannot seem to do this!
