ISP, FTTP, ADSL and alphabeti spaghetti advice

Was set to convert from copper to fibre on 28/1, appointment made by my isp, bought an updated router from them on their advice, ready for the new speeds@ £80.00

OR couldn’t connect, as the Splitter had been externally mounted, and needed repositioning

Then they told my ISP I had terminated the order

ISP then told me OR can’t connect my block due to “topography”- also they sent me an OR form to send to my Managing Agents, to request Fibre Connection to my block, so now I seem to be the Fibre Rep for the block

ISP have offered me SOGEA

Price has gone from £17.99 for copper, to £24.99 for fibre, to £28.99 for SOGEA

Also on ISP advice, I bought a sim router to cover the wait for the fibre connection which never came, at£100

At this point, after 2 months, I’m finding this just dreary and tiring, and am considering getting an unlimited Smarty data sim for 20 quid, and cancelling ISP, Open Reach and all attendant delays, confusions and miscommunications

Just wondered what your reaction and advices might be?

The only fibre available to me atm is All Bran
