False advertising and application process

I called Vodacom this morning to enquire about their tablet deal which only started on the 7th Jan according to their booklet. The consultant then processed my application and told me that the package was on "back order" and that i will be contacted for delivery once there is stock. I then get a call a few hours later stating that my application did not process which is not true because Sibusiso made me wait on the line until it processed and I even received 3 SMS's stating it was processed. Now i am told they cannot process the order because there is some note on system implying that the item is no longer on special. I refuse to accept this and you can listen to the call recordings. if i do not get the product i requested, i will be taking legal action on the matter. I will not be made a ****. i want urgent intervention on this matter
