Poor service delivering

Dear all.Don"t use this contractor for any of your renovations.Have used them and they offer to renovate my kitchen and bathroom with 1 st grade tiles.They using 2/3 grade tiles and tiles also differ.Tailing was not up to standard.Repair my braairooms roof and promised it will never leaked again but after 5 months it is leaking again.After sales service is non existing and after raising complains they just blocked me from their cellphones.You will waist your money by using them.
