Capacity problems on mast local to my home

[doublet]

Over the last 6 weeks I've been experiencing a very poor signal (0-2 bars) from my home address. It is very much worse in the evenings and results in calls being dropped, complete inability for one party to hear the other or just hearing garbled noise (like there's a dalek talking at the other end), and often when calls are dropped it is not possible to make another call at all for some time whereby my phone just says 'call ended' when I try. This is an extremely frustrating issue as I have no landline or other way to talk to anyone and my mobile phone does not support WiFi calling. Last year I experienced a very similar issue, again from at my home address, which took about 5/6 months for O2 to resolve. The issue was down to lack of capacity on the local mast and I'm fairly sure it's exactly the same problem I'm experiencing now. Despite the O2 status checker continually showing the network to be working fine, there is a note stating they'll be carrying out work on 23rd October 2023 to improve the network service in this area. I do not feel O2 is dealing with this issue sufficiently given the impact it causes and I'm not prepared to wait another 6 months for it to be fixed. Each time I report the problem I often receive a text a few days later saying the problem is resolved however the problems persist.

Any advice on dealing with this issue would be appreciated.

Thank you however after reading other threads on this issue it appears I was misled on the solution and the only way to resolve the issue is with a network reset. I'm currently waiting to speak to O2 customer services to insist on this as they seem to be the only ones able to escalate the issue to get this done.

Today I was contacted by the O2 Complaint Review Service and they were able to resolve the problem with the 'Unknown' caller ID very quickly and professionally by performing a disconnect/reconnect.

Last week I had insisted O2 customer services escalate the issue to get this done as they were unable to do it themselves.

Now I hope after the mast capacity is increased on 23rd October my call drop problems will also be resolved.

It is disappointing I've not yet found a solution to my Sony Xperia 5 not supporting wifi calling as this would be a great workaround though.

Thanks for everyone's advice and help so far.
