Fridge gas refill

My fridge stopped working last month and I found this swrvice provider on Google. I contacted them and they were very quick to come and refill my fridge gas. They said their service is six month guaranteed. Within a month my fridge stopped working again and when i contact them they are no longer available to assist. They make promises to come but they always don't come. I follow up with this company on a daily basis and they always say that they will come on the following day to fix my fridge but don't show. I will not recommend this company to anyone as they are acting like scammers and they are not accountable for their services.
