"Bad Customer Service"

I registered with the practice last week as i moved to the area. I understand at the time i got told it takes 2 weeks to be registered which was fine at the time. I am 12 weeks pregnant and i got a call from my midwife saying i have a urine infection and need antibiotics. I told her i have just registered and have been told it will take 2 weeks. she told me to contact the practice and explain the situation and just get an email from them so she can send the information so that i can get my prescription to which i did. my midwife then contacted me this morning to say she had a reply back from the practice to say im not registered patient at the practice. I then had to call the practice again explain the whole situation to then be told they will register me over the phone. Once they did that i then got told the doctor will call me on monday between 9am and 11am at this point i was getting annoyed and responded by saying i am pregnant i have an infection i need antibiotics you have the email from my midwife can a doctor just action it to which i got told they dont have the email as i wasn't registered. i responded by saying i am registered now over the phone so what if i get my midwife to resend the email to which they still said no and said we dont have any appointments today so it will have to be on monday. I then hung up the phone and called my midwife who was apalled by what i was told and said the fact the practice was saying they didnt have the email was untrue as she got a reply from them to say i wasnt registered. I then left it to my midwife to contact the practice. Once she had she called me back and she was annoyed she said she had an arguement with whoever she spoke to at the practice and instead she had contacted the hospital registrar and got the prescription done for me but i would have to pick it up from the hospital pharmacy. I understand they couldnt do anything by me speaking to them but this was another healthcare professional contacting them which is absolutely appalling and unproffessional. This also meant that i had to take time off work finish work early to then go from ilford to leytonstone by tube and bus as i dont drive to go to the hospital and pick up my antibiotics. I am very upset and annoyed and lets say i will be looking to register elsewhere because if i was treated like this over the phone whats it going to be like when im registered and need appointments. I would not reccomend this practice to anybody!
