POOR SERVICE

I had app**** for a cellphone deal on 16.07.2018. I received a SMS on 23.07.2018 saying that the application was declined. I then received a SMS on 30.07.2018 telling me that my application was pre-approved and that a debit order will be done within 3 days. A debit order was done from my bank account on 31.07.2018. I have been contacting the Call Centre everyday since 01.08.2018 and without any joy. I am given a different response everyday and that the matter was escalated to the Manager. This is going on for many days. I have not received any feedback either telephonic, e-mail or SMS. Please note that I have not received any device from Telkom. The SMS for 30.07.2018 is considered to have over written the SMS sent on the 23.07.2018. I am starting think whether this is a *****alent act and all that I want is a proper answer.
