Bad service MONDO

Mondo offered contract. Promised a DUAL sim as this is the only one i would accept. Repeated to me on recording that it will be a Dual Sim with memory slot... got the phone and it's a single sim... Excuse is 'sorry, Vodacom does not do Dual sim, would you like to cancel the contract" ***!! you wasting my time and energy with this false advertising/sales. Ms Singh... i think you need to look for another job! No proper apology or explanation from Mondo. Will not deal with them ever again! cancelling this contract..... BAD SERVICE
