Bad service and bad connection

I've been a loyal customer making use of your service for more than 2 years now not giving you guys any problems with payments but look at what weak customer service you are providing me with, it's been like 2 or 3 months since fiber has been in my area and I've been making contact with your company's sales department trying switch over to fiber but have not been able to get helped. I've waited long enough now without getting any positive feedback and to top it all off this adsl plan I'm currently on has been too much of an inconvenience the last few days as it kept on disconnecting, so if my problem doesn't get addressed soon I'll have to leave and insearch of better service elsewhere
