Shocking service from Telkom

I placed an online order with Telkom for a Samsung se5 tablet on 21 May 2019 an I was assured that the tablet would be delivered to me within 7 working days (delivery should have taken place for the latest by 31 May 2019). Note, the payment was deducted on 24 May 2019. On 25 May 2019 I was informed by Telkom via SMS that they are awaiting new stock and I will be updated when new stock was available. No update has ever been provided. After more time I called the Telkom call centre on 3 June 2019 and was advised that they have received new stock and my order can be processed however I must wait a further 7 - 21 business days in order to receive the device. I called again on the 6th and 13th June 2019 and the only feedback that I got was that they are working on my order. It is now the 17th of June and I still haven't received my device and I am m appalled at the pathetic service rendered by Telkom. I need my device to be delivered to me no later than close of business on Tuesday 18 June 2019. The service that I have received is shocking and I've been a loyal Telkom customer for more than 4 years. Rectify this ASAP.
