Dual sim phones on contract

I have sent Vodacom from their online e-mail address two days ago and did not receive any response!<br> <br> I have tried to make contact with a senior sales person via the call centre ***. I have spoken to four different people and hold on for 16+ minutes and then put down.<br> <br> My problem is as follows:- (1) Vodacom sells pre-paid dual sim phones via Metro (2) I have bought a dual sim phone and use my two Vodacom contract sim cards in this phone, without a problem (3) Vodacom cannot tell me why they do not sell dual sim phones on contracts!!<br> <br> Communication with the entry level personnel is of no value and you do not get to speak to senior management and e-mails do not get answered.<br> <br> As a client for the past 10+ years with at least 5 contracts on my name, they force me to go to their opposition.
