BAD SERVICE TO FIX A FAULT

As a long standing loyal customer for 15 years, last week my landline and ADSL was cutoff, no explanation. I have raised faults ***6 & ***9 and tried to get it resolved through numerous avenues, but no response. Everytime I contact the call centre someone gives different information, still no fixing of the lines. I am so cross, this is now the only platform to put out my dissatisfaction with this company, as NO One is helping sort this out.
