Uncanceled wrongly added contract becoming a Forced contract by Sales department & Vodacom miscommunication

Vodavom Sales Consultant called me early November saying I should take a Gadget onto my month to month contract that is giving me Airtime ONLY. The contract has . been there since 2014. Because of no network in Delmas I proceeded to use online sales to pick a gadget but Vodacom Created a new contract adding to my profile early December, on Receipt of the Statement the New Contract Vodacom Was Flagged on the Miscommunication & mistake of the additional contract created on my profile, the Twitter team responded & and after a week of communication the Sales department promised to cancel this additional contract & pick up the gadget as it was wrongly added onto my profile. I packed up the gadget &: everything recieved with it ready for pickup by the courier as promised by the Twitter team. Because couriers were busy in December and came thru on 23 December for the pickup only to find that my workplace had already closed for Holidays. Vodacom was alerted on this & they promised to pick up the packed set aside gadget in January. Come January I have called, requesting the gadget pick up but Vodacom sales department has just ignored me, telling me they are escalating the issues endlessly. This gadget is still packed & waiting for pickup by Vodacom courier to pick up. Worse the Vodacom communication teams don't coordinate to give one word to customers. Each one you speak to does not give clarification on profile, one says something else and another does something different which frustrates customers. This is a night Mare as sales is simple pushing sales without acknowledge how the customer profile should be, I don't need this extra contract and want Vodacom to cancel it as promised. I have all communication of this cancellation by Vodacom from their Twitter team.
