Poor service

Last month I signed a contract with this company, they delivered the device and next thing I know, they attempted a failed debit order on my account. This was done outside of the agreed monthly installment, after that I received a message prompting me to make payment arrangements or risk the suspension of their services. What frustrates me about this is that I never even received a courtesy call from the company to check whether I'm consuming their services, whether I managed to connect etc. Because their device is still at home and not yet installed but are quick for debit orders. In essence this company wanted to charge me for the service that does not exist, that is day light *******. I called them and they promised to resolve the matter and until now nothing has happened. I'm less than a month with this company and there is already issues, this is seriously worrying.
