Whatever is going on with Vox.

I logged a call through email with Vox on the 2nd of August, and as per usual, received an automated response.I followed up theojgh another email on 6 August as I really needed to know if my issue was being dealt with, mostly because that was probably the 4th call being logged for dropping internet connections & low speeds (I work from home mostly). Instead of any response on email, a technician then called me, I was not at home that day & asked to be called the following morning @ 8,my meetings start at 9 & I connect to multiple remote servers for work.He agreed & raised no issue with 8 except he didn't call.It's beeb a back & forth with peepa not telling me they can't call at 8 and calling at their own time, I raised all of this on emails,where I was talking to myself as nobody ever responded.The other person called & I said look, let me disconnect my work things,coz u guys agree to 8 & never call, rhen call me after 5 mins so we then troubleshoot, he said cool, did not call after 5 mins, when I had disconnected everything.The last person called later, said there were no notes about me asking to be called at 8.I said ok, close that call logged,I'm done with you guys. Days pass, this morning 14.08 I get bombarded with 5 missed calls, and an email saying they received my request to cancel the service due to no connection.I asked for the details of the peraon that put that request through, nobody responded.I took this to Twitter (now called X) but I was ignored as they were responding to other people but not me. So clearly Vox is saying they will not comms, they will not honour our requests as customers & if we enquire, our service will be cancelled. If I went to the ombudsman, would they tell me this is a fair way of being treated as a customer? For a service that I pay for?
