Site keeps having stubborn flaws! Discovering new flaws all the time. Really need assistance ASAP!

L.S.

Sites keeps giving stubborn issues! Some issues I have reported on before but I have never received any response(!).

Each time I discover more flaws. Whole sections missing, or appearing weird and all crooked on the web-page (not in the builder). Now I have also discovered that pages that look OK on a PC could look all twisted on a phone or tablet.

Can I have someone please help remedy these bugs?! My site represents my business!
