Intermittent Internet

Our internet has been intermittent, we contacted the contact centre on the 3rd of October already yet we still have the same issues. my isp advises that all that is needed is our line to be reset, but apparently that has to happen every two months when we contact you because either the landline or our net is down. Can you not do anything right? or do you enjoy providing lack lustre service so that your contact centre is flooded with queries and we then have to use the useless website, which takes about an hour because my internet switches off every 5 mins. I am surprised I can log this complaint, after about 30 mins of waiting for net. Anyway our fault number is 45CWK031015. the person who generally deals with you has given up since you guys don't really do anything. Please contact me, so that we can resolve this matter.
