Very Bad Service

I have reported 3 Faults within a 1 month period. First on the ***5 was resolved ***5 exactly a week after I reported the fault. Secondly on the ***5 was resolved 4 days later. Thirdly reported a fault on ***5 and not yet resolved. As this is a repeat fault I expect this to be treated as higher priority. What happened to your service levels it went from BAD to better to WORSE than ever. I also expect my bill to be adjusted accordingly. When can I expect this to be resolved permanently???
