Sero Construction Inc

Hi,i have a bad experience with sero Constraction ink,the company owner name is Serhatcad,he painted my outside staires,but because of sun ,was hard to see ...,but he said if something is wrong,let him know,he gives his warranty for 5 years, which is nice,the next day i called him and said there are few spots that have to be fixed,he said he will come to fix it ...i was waiting for him almost two weeks and nothing... i texted him that i cannot wait forever,and if he is not coming ,i will file a company complain,i paid him cash but he also asked for tax,he said i am exaggerating,and texted to me very disrespectable way instead ...
