Poor service

This is the worst service provider.I app**** telephonically for internet at the beginning of September,to be installed on 1st October as I was still with my previous provider until then.They brought my router on 1st October and vumatel only released the line on 2nd.It took me numerous e-mais and phone calls before I was eventually connected on 5th. I have been billed pro rata for 2 weeks in September.Vox says that we are billed on application and have threatened to stop my service.Customer care and call center are useles and no one returns my calls.
