Very Bad Service!!!

Since I paid my account 3rd of July 2023 and they told me no payment received. I have sent multiple emails with my proof of payment and no one is responding to any of emails. The service is very bad no communication at all and every time I call I always get same story, which is I should send proof of payment when I tell them I already did thy tell me to wait 5-7 working days. Which is what I did and when I call again they tell me to wait again it's been 3 weeks now the issue is not resolved and am tired of calling. The service is very poor as the consults will tell different stories saying they did not receive my documents and others saying they get back to me, wow!!!!
