We had a mobile mechanic come out to do road worthy said we needed to do a few things ,I rang him and said we were going to do repairs ourselves ,he was cheery as I explained my son was having a problem with part of the repairs ,said he'd advise if we sent a pic. Days later I ring x3 then msg nothing ,repairs are done now and he's still not answering to review safety cert soopo ,can anyone advise me on whether another mechanic will sign off or do I go through whole process again ? My sons car is now unregistered and just want it back on road . I have been ringing this guy since wed last week .
