123-reg seem to have problems with renewals.

in April i renewed one of my domains, received receipt from 123-reg and paypal, nothing wrong with that until June i noticed that when i want to do some work and then check this the URL brought up a holding page on further checks i found that the registered name had changed along with the TAG, so i contacted 123-reg and when they failed to reply i contacted Nominet, who told me that this was cancelled through my nominet account, i provided evidence that this was not me and i have paid for the 2 years renewal. with the evidence nominet gave me back the domain, but then 123-reg started demanding the reneal fee even after i provided evidence from their own system, paypal and my bank, but they still insist that this was not paid as they cant find any record on their system, now they are giving me 7 days to pay or my domain will be suspended pending cancellation until i pay them again.

I would say this is a very elaborate scam to get me to pay twice.
