Non-existent Technical Service - Fibre

<p>My internet connection keeps on going down in the evening. It seems to be getting worse - it is up for a minute or two and then it goes down for 5 minutes - so my internet is effectively unusable when I want to use it the most. I have contacted MWeb technical support - they were supposed to phone me back last week - NOTHING. I have sent numerous eMails and I get an autoreply to say it's been received. One of their technical staff phoned me on 3 June (over 2 weeks ago) and told me to try ping the router and ping an internet address when the line drops. He was going to phone me the following day to find out the results. NOTHING. I phoned again and was told somone would contact me last Friday evening. NOTHING. Phoning their call centre is usually a painful and costly experience - waiting for 30 mins or more (I need to use my cell phone as I have VOIP with them also!) . WHY ARE THEY SO BAD!!!!??????</p>
