My phone has loud crackling

[J+Clapson]

My phone has a loud crackling noise, which makes it very hard to hear someone speaking. I have tested the microfilter by removing them and putting the phone directly into the bt connection. It still has loud crackling.

@J+ClapsonIs your broadband working properly?

[J+Clapson]

Yes the broadband is working.

@J+ClapsonIs the crackling bad that you can't hear the other person on the other end speaking?

Do you have another means of reporting this fault to Sky, like through using a mobile phone?
