4G no internet, no service and constantly on E since 3G shutdown

[Rxbski]

Ever since the 3G shutdown, I have been getting 4G no internet in most places that never before, even if I have full bars 4G or even 5G, it just doesn’t work at all! Vodafone customer service don’t care in the slightest as it’s “good” on their end, and also in areas where I used to get amazing 4G or 3G I now only get EDGE connection, no service or just 0 bars. I’ve raised the complaint with Vodafone 3 times and nothings been done to fix the faults. 
I’ve switched to E-sim, tried it on both a Samsung galaxy s23 ultra and a iPhone 14 Pro, I’ve configured all my APN settings and done the basic troubleshooting and I still get no connection it’s unbearable. My signal does work sometimes, but only in limited areas, I feel like a o2 user.
If anyone had a fix to this I would be so greatful. Thank you

Although it is very frustrating for all I am pleased to hear it is not just me! The connection around south London has become so awful and even visiting other cities. Friends on O2 have good 4G signal but I am stuck on EDGE half the time.  I received replacement SIM but obviously issue still remained... I don't know why customer service are still saying no issues with network... thought surely it would've been resolved by now!

Just spent a fruitless hour on the online chat on this subject. Before the 3G switch off we had a reasonable service in semi-rural Suffolk if phones were forced into 3G mode. When the switch off was announced I queried whether the 4G service would be improved beforehand and I was assured that we would not lose service. Here we are, not able to make or receive calls reliably and with no mobile data. Many in this rapidly growing (7000+) village have the same issue despite the coverage checker saying it's good. I can only assume it's the contention issue although the signal strength according to WiGLE is -116dBm which is on the weak side for LTE (100dBm is the threshold for good coverage).
