STEELING OF AIRTIME AND MONEY AFTER CANCELLATION

We cancelled one of our contracts with Vodacom as from 1 April 2018. Big was our surprise that the morning of 31 March 2018 all our airtime and data disappeared. On calling Vodacom the customer care says it is according our terms and conditions. I feel that we paid until midnight of 31 March and you should have airtime until then not loose it 14 hours before the time. They should the credit a person for the last day of the month if they are doing to it.
