"Continuing poor service / standards"

Continuing poor service - losing confidence in management of my care. Long telephone wait calls seems now an accepted norm so.. In the past I have been given another patients medicince - feels slapdash. Recent experience of speaking with receptionist to book bloodtest was a horrid experience - rude and very defensive. Last straw was calling for test results this afternoon to be told by receptionist a GP looked at my results - cholesterol 6.9 - and to continue taking medication - no further action. worryingly I am not on cholesterol medication so. I was told by receptionist to call tomorrow for appointment to discuss with GP. If I hadnt chased this then my high cholesterol would go unchecked? I feel this just adds weight to my concern practice is in a chaotic and slapdash. I assume this is down to lack of staff etc but for a GP not to check my records, or mix me up with someone else? I would like your comments please.
