Bad Service

I'm extremely unhappy ,Vodacom disconnected my phone due to nonpayment ,I paid full amount on Friday it's been a struggle since then to reactivate my phone I've been to the Vodacom shop a few times spoke to numerous people and still no luck it's been 4 days and no one takes responsibility payment was late I do understand that but why must it take so long to reactive I even went in today and did a sim swop and that didn't even work ,I'm so frustrated please could someone sort this out !!!!!!
