Upgrade never done

<p>Went into vodacom shop end of August, spent 2 hours upgrading to a Uchoose 350. By the 7th the upgrade had not happened yet, the lady at the Piet Retief shop, Ayanda, said it was due to there being a lot of upgrades but I should just be patient it should be sorted out shortly.... Debit order came back into my account, for no reason as there was sufficiant funds available, I reckoned it was a mistake on their part because they didn't do the upgrade yet... now I keep getting calls for none payment. Exactly what does vodacom want payment for as no services were rendered... The upgrade I did at end august has still not taken effect....</p>
