Query still not resolved!!!

<p>Over a month ago I lodged a complaint about my ********** upgrade - EC-047J-2J3PAQ .</p> <p>After investigations , the investigators could still not explain why I was told I upgraded as the system shows I ported my number.</p> <p>In the meantime Vodacom has continued to try to deduct. Today I recieved a letter about missed payments with threat of being listed with ITC!!!</p> <p> </p> <p>Vodacom - what must I do?????????? No one seems to care to resolve my query!</p> <p> </p> <p>This is really really dissappointing.</p>
