Shocking service and communication s****s

So it took 6 weeks for installation with no explanation I fact no communication from SADV until my service provider had to get involved and escalate it. Wednesday morning installation was done, very pleased with the technician as he was very friendly. and was told that I need to wait for them to connect me remotely he has logged my installation. My service provider came on Saturday and installed my router as they got the okay from SADV but still no remote connection we are force to use SADV I think you take this to your advantage to offer the worse service someone could possibly get. Some communication from ones side would be great and this is not blamed on the pandemic we facing this has been going on since before the pandemic.
