Only good for a while

Called fault reporting early Sept. My internet is so slow lately that impossoble to work on.Was not like this when had it first few months.Call centre tells me someone will call to look at settings.No one calls. Fault says resolved. Send sms to ask if was resolved. Send back no. NOTHING happens again. So, log fault AGAIN 01/10/2015. Call centre agrees something wrong. Download speed is 0.80. Upload is 0.18. Ping is 500-700 ms!! Thats not DSL quality-worse latency than 3G! Get sms to say fault logged and immediately to say resolved?? HOW IN 2 SECONDS? And internet just the same or worse!!!<br> Call back and log fault for THIRD time!! Please stop wasting my time and fix whatever is wrong!!!<br> <br> And after NUMEROUS emails and complaints, my bill reflects a ADSL contract?? WHY?? Please listen to sales call-i requested NUMEROUS times i dont want a contract and sales person assured me its not a 24 months contract!! Listen to the call! The proof is there! Everyone promises to fix but never happens.<br> <br> Are contracts given without consent so that it forces clients to remain with the service when the product declines after a few months??
