Very disappointed customer

I hate to leave any form of bad review but unfortunately in this case it's something that can't be avoided. I've been with Tech5 for nearly 2 months now as unfortunately where I've moved to they only use Tech5 (very sad indeed) but initially signed up with a 50mb line to find out they installed and set up for a 10mb line 1st issue, then the line was never consistent with network coverage or anything was told it will be esculated and will get feed back never got any response 2nd issue, and then whenever speeds tests were done got ridiculous low readings was then told the upgrade to a 50mb line was complete and issues will be sorted still to this day nothing is sorted they never make any contact or effort to contact me I'm always needing to make first contact and get told the same ridiculous story each and every time. At the point of wanting to cancel with them but got a problem of the place I'm in only uses Tech5 so don't know what to do. There service is absolute shocking
