E-filling issues

Since the 1st of July 2017 we have been trying to get help from SARS Call Center with no luck. My husband's e-filling profile is been registered under a tax practitioner and now we unable to submit his tax returns for 2017 but it was done by a practitioner before. We requested for his file to deleted or removed from that practitioners because we unable to find him. My husband can't go to SARS office to submits manually since his not well. Can we pls get some sort of help to this issues to be sorted out. We called customer care center so many times but none of consultant can't help us.
