I parked in NCP Bournemouth. Machine was problematic and I tried several times before using phone to get help. Got no answer. A lady helped me and the machine finally” pinged “ which I was told meant payment went through. 3 weeks later I receive a fine for £100 for non payment. I checked my bank statement and seems it did t go through . I genuinely believed it had .tried to appeal but they wernt having it! They offered to extend the £60 fast payment but that’s still ridiculous for only 30 minutes parking. I believe this machine has caused others problems too. Will never use their car parks again
