"Extremely poor level of care"

I was admitted to the surgical ward in December and February and on neither occasion was I satisfied with the level of care from the staff. In December I was admitted to have my appendix removed , to only find out 5 hours after the surgery that I hadn't Infact had this done but another procedure, my file disappeared several times during my 3 day stay which meant I wasn't able to receive pain relief when needed. After my first night I was never checked on during the night or given again pain relief despite being in agony. When i rang the call bell was treated as if I was disturbing the staff. I then returned in February with further problems , admitted to the same ward from a&e (who were lovely), I went via RATU (who were also lovely) but once I got put on the ward I was left. I was due a scan which I never had, never seen a consultant until discharge, I stayed for 2 days with no tests carried out and again my file was lost at least twice. On 2 occasions I waited over 2 hours for pain relief. I was discharged and told I would need to come in as an out patient for further tests... I am extremely unsatisfied with the level of care at the hospital. And I am still suffering with problems and not had any answers. I would appreciate being contacted by someone for feedback on this.
