Incomplete application process

I was called by Caroline from Mondo Rewards(in association with Vodacom) on 28/01/2015 offering an additional line of data of 1gig p/m at R89 p/m. I accepted the deal and she asked me to send documentation to her which I did. I kept following up on the application to no success. Today I get called by Suren to offer the same deal but now at R109p/m and when he vetted the application it was immediately approved, which goes to show that my documents were received! It is very unfair that I now have to pay a higher rate when I was initially offered the same deal at less and the reason was due to consultant negligence. Thank you to Suren for his prompt assistance but I would still want to pay the initial rate I was offered. I am extremely disappointed. What makes it worse is I sent Caroline an e-mail to her personal box requesting feedback but she did not respond. This is not acceptable. I understand that they were offering me a deal but do not poke at the bear and then expect it to remain still.
