Airtime and data depleting just after loading it

<p>This is the third time I'm having this same problem I'm now gatvol of vodacom. I loaded airtime and data and in less than a minute of loading it I got an sms that it's finished, I've had this same problem before in December 2015 and in March 2016 . This issue was resolved in March wen a technician phoned me and she advised that all Internet connections under settings must be switched off and we found out that all was already off. I phoned the vodacom call center on ref S3gv43rrrlgx and spoke to zanele & tumelo who was not helpful and cld not refund me my data and airtime. And said I have to wait till Tuesday and in the mean time if I load airtime again it's just going to disappear and there is nothing they can do, I want this issue resolved and I want all my airtime refunded,</p>
