Vox horrible experience

I subscribed on vox in 2021 with TT connect connection was good and I was receiving the speed I signed up for till November 2022 I started having connection problems continuously and was advised that it is due to the heavy rains, that continued till April where there were not rain at all. I then decided to cancel the contract with Vox and TT connect, whilst I was looking for new service provider I saw open serve option my mistake was to go with Vox again on Open serve. I regret every minute it has been the worst nightmare ever worst than TT connect, the router was installed in a very awkward space where the signal goes to my garage and on my street but nothing in the house, I am lucky to have connection let alone the speed I am paying for, if I get 7mbps down and 3 up it is a lucky day whilst I am paying for 75 and 50 respectively. I have called vox almost everyday and nothing is changing, and when I advised about the installation done in a wrong place I was told I must pay call out fee for technician, whilst the same technician installed where we advised against, now it is our problem.
