Bulldog isp ermelo

I am a client at bulldog broadbrand in ermelo. I struggle with my wifi signal and if i try to get some answers no one answer. If i call no one answer. You know i am a paying customer so what now. If you don't help your clients you wil lose paying clients. WHY MUST I PAY IF I DON'T GET SERVICE. VERY BAD SERVICE. THE PEOPLE AT BULLDOG BROADBRAND JUST KNOW YOU WHEN YOU OWE THEM MONEY OR THEY HEAR YOU HAVE MONEY BUT WHEN IT COMES TO SERVICE THEY IGNORE YOU
