"Bad customer service"

Due to incurring major back pain and problems with my chest i have had to visit the surgery several times and was referred to a+e as as it was severe. I have since had to have various x-rays which have had to be referred to from my gp. So hence i have been back and forth from the surgery to the hospital for some time. I realise that there are various procedures that are involved in the medical profession and i am aware of this. However after suffering from the extreme pain that i am currently going through i was advised after my last x-ray to get some more medicated cream from my gp to help ease the pain before any surgery is confirmed and undertaken. I eventually got through to my surgery and spoke to a receptionist and she advised me that they would get my gp to reissue my medicated cream has it had run out. I was told to ring back later and spoke to a receptionist again. My call was then passed onto someone else who advised that i'd had too much cream( i've only had 2 tubes in 8 weeks!) and that i should buy it over the counter at the chemist or i could go the pound shop!?! I replied that i would i attend a+e as i was in severe pain to which she replied that i would be wasting nhs time!?! As i have been suffering with severe pain for some time i had.already purchased cream from the pound shop previously which reacted to my skin and had actually burnt it. Overall the service i have received from the surgery has been diabolical and i will be taking it further.
