Poor service delivery

We have been clients with Home Cloud since November 2017 and have had numerous problems with their service, poor customer service and no contactable numbers. They make debit order deductions prior to debit order dates as arranged, then switch off the service due to non payment, they request proof that this has occurred, as if one would lie about something like this, and then still does not sort out the account. Emails, phone calls, has no effect, they will get back to me, but still does not. Contact numbers listed on their website is non-existent, and the service is extremely poor. My wi-fi has been off since Wednesday, 23rd January, once again, due to non-payment, according to them, numerous phone calls to them, with promises that someone will call me back from the accounts department, but all to no avail. Their after hours number, again, non-existent. I am quite sick and tired of this matter.
