Bad experience with the company

I order a landline via them, the say to me it's a rental not contract which I was interested. They did not explained to me if I skip month not paying for another month I will loose the benefits of that particular. month, as I am pub owner and bottle storeI decided not to pay due to restrictions of ban of alcohol and no one was working on the store the was no need for landline. Now the are busy emailing me the invoices even I'm no longer renting their services. I will not encourage anyone to use their service.
