@Home online disappoints

On Saturday 9 June 2018 I noticed an online promotion for @Home in terms of which a R5000 discount would apply if furniture which is not discounted is bought to the value of R20000. I visited my closest @Home store to view the items and the staff was not aware of the promotion and confirmed I should make the puchase online. I proceeded with the transaction on Sun 10 June and entered the code save25. R5000 was deducted from my order exceeding R22000. I chose to pay by credit card and then the screen changed immediately to state my order was succesful, my order number is *** ********** . I called the TFG helpline the next day to report that I did not receive a mail directing me to a credit card payment and asked if I should go to a store to pay. I am a TFG cardholder. For the past 7 days I received no response from @Home to assist me with my order. I want to make a purchase but they seem disinterested. My guests arrive this weekend and my spare room will not be furnished due to this delay.
