Vodafone — My service is stopped inspite of payment

I had paid my postpaid bill through vodafone website using american express credit card, but my service is stopped, they resumed the service for a brief period after a few emails ( I sent them multiple screeshots of confirmation emails sent by bank, and also the transaction ids), yet they have stopped my service, I have sent them the credit card statement, which clearly shows payment is sone, yet no response
