Two pots nightmare

My issues are far from over with Liberty, i had an issue with being over tax by R5k extra only to find out that the income provided to SARS was not my actual income since there was a blank space on the numbers when i typed my income, I then went to Sars and they said Liberty is the only one who can assist me in order for me to get my money, and i tried calling and explaining but they still maintain that there's nothing they can do on their side, its frustrating to be left hanging honestly this two pot thing is a nightmare with Liberty.
