Paying for a product that has not been delivered

Paying for a product that has not been delivered Absolutely poor service. I made an online application for a mobile contract on the 25th of March 2020. I received a phone call to complete the application. I then received an SMS stating that a vetting process would now take place and I would receive a call back within 48 hours and I have been pre-approved. The phone call never happened. To my surprise, a debit order went off on the 26th for the contract. I still did not even have a reference number or even a phone call to explain the terms and conditions of the contract. After numerous phone calls and emails. I finally received communication on Monday( 6th April 2020) but to my avail, another SMS saying I have been pre-approved and my order will be processed. How Telkom? you have already debited my account. I called in a spoke to a lady who was informed that the device will be delivered in 2 - 5 days. 5 Days later nothing. Called again after 5 days and I was told y a different lady it will take 7-12 working days and they will expedite the delivery. Its 15 days later and once again not a single form of communication from Telkom's part as well as no delivery of my device. I understand that we are going through a pandemic but all I want communication and not empty promises!

How many calls, emails & escalations need to take place before I can either get the mobile device delivered or communication when I will be receiving the device?
