Mondo has not fullfilled its obligation with regards to delivering my cellphone

On the 19th of September, I received a call from the Mondo consultants to confirm that I qualify for the cellphone contract I app**** for. The consultants took my details, did a credit check and confirmed that I qualify for the package. He said that I should send my 3 months bank statement, a copy of my pay slip and a copy of my ID to ***. I did that and got an email that my documents were received. However I still don't have my phone, I was told that it will be delivered within 3 to 7 working days, and we are already in October.
