IRP5 not amended with SARS

I tried to file my tax return via the SARS efiling website and received a tax directive to send to Sanlam to sort out the tax calculation and amend my IRP5 with SARS. I sent an email to customer service and they responded with an IRP5 to upload on the SARS website. The tax directive clearly stated that Sanlam should amend my IRP5 sent to them and there is no option on the website to upload the IRP5 communicated. I have tried to communicate this with customer service to assist me further, however there has been no response. I'm very disappointed at the service provided by Sanlam to their customers when they promise the best service.
