No emailed contract

I upgraded my cellphone contract on 1 February at MTN at Century City. I took a new promotion but the sales consultant was unable to load it and said he would do so manually. He did not give me a copy of the contract as I requested an electronic copy be emailed. He promised to email me once the contract was loaded. I received an sms on 2 February to say I was successfully upgraded. I have not yet received my contract. I emailed MTN's customer care on 6 February to request the contract. I received a response 6 days later from Zulpha Adakarie at <br> Customer Services at MTN SA saying that the request had been escalated to Corporate Accounts for assistance. As yet I have not received any further communication. And still no contract!
