Sanral
Incorrect account

I have receive an sms that i need to pay my etoll account, after i have phoned sanral they told me that i need to contact a third party which deals with the VPC and they do not have a direct number they can transfer me only, which they did, but to no avail,
After then checking the VPC number on the sanral website, it claims the VPC has no outstanding transactions??? How does this work must I pay or not???

Today wanted to buy a DAYPASS on the sanral website for todays trips to JHB, but seems like the website does not accept ecommerce payments...
