If u want to speak good english, practice more is the best way, but if you are looking for a job now, I think it's too late for u to practice now.
May be you can call the company you apply for and ask them whether they have called you before, you can use 'the network has some problems and you can't hear very clearly that time' as an excuse. BUT REMEMBER, don't be nervous this time, hear it with all your attention, if you have lived in UK before, I think it will not border you.
In fact, if they call you speaking in english, I think the english usage will be very important in the interview, do prepare more, likes go through the website of the company, it can help you to have full knowledge about the company, including the job profile etc.. And try to speak more in daily life before interview, it can make you accustom to speak in english, so can help you to speak more fluent in the interview.
Practice makes perfect is always right in oral. Read more and speak more, I think you are just too nervous and cannot 'tune' your channel to english suddenly, but not a real problem to you if you can overcome your nervousness.
Keep calm and don't be nervous, if you can't really hear very clear, don't feel shame to say excuse me or sorry, I think they will repeat again. Good luck!!
