ISP service dropping

Constant internet problems with this ISP, you have a service that works alright for a few months after my last complaint that I had to submit for my landlord because he is visually impaired. Then all of a sudden there is constant line dropping and without warning. When I call your staff always reply with I see nothing wrong. The issues are at 10am, 12-14pm, 19pm and onwards till 22pm.

Frankly i need solutions or i should just move to a different ISP because fighting over the same issues over and over again is tiring. I'm tired of contently reporting how about you contact me for solutions now

I will be happy to retract my statement if something is done.
