Double Deal Black Friday special not received

On the 24th of November 2017 at 9am I went to Vodacom 4 u in Carlton Centre to upgrade my contract because there was a double deal special of P10 and P9 for R249 per month. Till today I have been sent from pillar to post. I called again on the 4th of January 2018 Lillian answered the phone and she said they are still waiting for deliveries. I called their sales and distribution the lady who answered the phone said they are not telling the truth they must give me phones. They said the deal is extended to much because of delay in delivery.
