Trash ISP

So for the 4th time in 3 weeks I am experiencing technical issues (as I usually do once or twice every month) with this product. I have never struggled this much with an ISP. I pay R899 a month for a 50/50 mbps line (this month is suppose to be 100/100 by the way) but I get max 10/10 mbps not to mention the constant disconnections. They always give you some generic excuse like 'we are doing maintenance etc'. My problem is that they don't keep their clients informed of the situation. I haven't received an email with regards to the maintenance schedule etc. I get that it is difficult with the current climate in the country but excuses can only be made to a certain point.

I can't wait for this month to end so I can cancel my subscription an move to a more competent ISP.
