Poor Service on Upgrade

Early November I was contacted y Telkom for an upgrade on my current ADSL line. I had already looked into LTE and was very happy to agree to the upgrade. We did the contract over the phone which included a rooter and sim which I was going to receive in the next tow weeks. The new deduction was also going to be effective on the 1st of December. At the end of December i have not received any further communication from Telkom. At the end of December after numerous un-answered calls to the LTE sales department I opted for the uncapped promotion which was successful (ticket number #***). Again i have not heard back from Telkom. I have spent over three hours to the sales call center with no one answering. I have gone into Telkom shop in Cresta and they also could not access the system to see the status of the application. This is now almost three moths of NO service at all. I was even promised a call back which of course never happened. This in my opinion is absolutely POOR service of a new sale.
