Account paid, but line still remains locked after 2.5 days

<p>On the 5th of July I paid my Vodacom account in full and shortly afterwards I received an sms where they confirmed that they did receive payment and that there is no need for me to submit proof of payment. On the morning of the 6th I phone them to ask when my line will be unblocked and they informed me that it could take up to 24hr's. This morning I phoned again and they indicated that it will take 2 hrs, after two hours I phoned again and they indicated that it would take 2 - 5 hrs. After 5 hr's I phoned again and I only got a voice prompt telling me that they have picked up I phoned a couple of times during the day and that I must leave my number and they will get back to me. Just after 17:00 I phoned their customer care line and they informed me that there is nothing they can do as their accounts department closed at 17:00 and I must wait until tomorrow. WHAT REALLY BAD SERVICE.</p>
