no delivery and lack of feedback

it is now over a month that i ordered a tablet. the initial tab ordered was a samsung tab-s and after waiting for 3 weeks without any feedback i called the contact centre and was informed that the tab has been discontinued. i then opted for an apple ipad and its now over 2 weeks and still have no feedback. i have called again and was put on hold for 15 minutes and then cut off. a debit order was run on my account and i do not have the goods i paid for. i want my money back and terminate this pathetic and poor service with telkom.
