DISAPPOINTED WITH THE SERVICE I RECEIVED FROM SARS

I am so disappointed at sars for not responding to my objection for auto assessment outcome,They were very quick to bring a third party to collect what they call debs from me without them doing a thorough check on my profile.They sent a correspondence to say I owe them the amout of R500 for the tax year 2022,I objected that but they did not respond to my objection,all they did was ro send another correspondence to say I owe R2500 including arears,another objection was sent to them but no reply,then they sent another correspondence with amount of R6000 ,objection sent but at no avail.My question to them how do I owe them for 2022 while they paid R600 in my account as my returns of rhe same year they say I owe the.And what confuses me is the company I worked for was the one always deducting a pay as you earn every month until it went on a bussiness rescue on the 27th of July 2021,this needs to be resolved because by the look of things my name will be spoild for nothing.I tried so many times to call the toll free number without getting any help.
