Looking at the dates, and ignoring much of what you have written to make sense of those dates (because what you have written is Grade A hogwash), we can conclude (for the sake of the sanity of anyone else trying to help) that -
May 2025 - either alleged speeding offence occurred, or NIP issued. Or both, but either way, that "speeding ticket" the OP received then was never received as he no longer had access to the address on the V5C.
June 2025 - offence contrary to s. 172(3) RTA 1988 was deemed to have been committed when no response to the requirement in the NIP to name the driver was received at the expiration of the 28 days beginning with the date of deemed service.
November 2025 (probably) - most likely an SJPN - either for the s. 172 only, or for both the s. 172 and speeding was issued, and not received.
27th February 2026 - for reasons not entirely obvious, rather than the SJ simply deciding the case on the papers as no plea had been entered, a court hearing was held to try the information. Notice of court hearing date possibly sent in November 2025. OP convcited of s. 172 offence - 6 points, MS90 endorsement code.
DVLA endorses OP's driver record and issues notice of revocation.
Monday 16th (presumably March 2026), OP received notice of revocation from the DVLA, given notice of date of licence revocation. OP phones the DVLA. OP calls the Service Justice System?
Tuesday 17th (also presumably March 2026). No idea what was said.
On the assumption that you first became aware of the court proceedings on Monday 16th March, you effectively have 4 options -
make a statutory declaration within 21 days of becoming aware of the proceedings and have the conviction quashed under s. 14 MCA 1980 (why you were unaware is irrelevant to the process) - if made within 21 days, the court have to do this,
request that the court re-open the case under s. 142 MCA 1980 in the interests of justice (don't do this - it is at the court's discretion),
appeal to the Crown Court (again don't do this - costs can be higher, and more importantly this would be your second bite at the cherry, quashing and having the case reheard in the Magistrates would be the first bite (a second time), still leaving the option of an appeal to the Crown Court open, or
do nothing - depending on what offences you were charged with, and the viability of any defences at a re-hearing, and numerous other things we have not been told, it is not always worth going through the process if the outcome is likely to be substantially the same.
Please do not use jargon and/or abbreviation unless you are sure that both you and we understand their meaning.
Also understand that you are facing a serious issue, and that we have better things to do with our time than pulling teeth and trying to distill meaningful information from gibberish.
