Hi Mrs Magoo,
Thanks for the PM, sorry to hear you're experiencing problems again. So just to confirm, the crackle has got worse? Is it intermittent or there all the time?
Ok Debbie il have a go , but this socket was put in by bt, and its only got one thing plugged into it as its one of them that has a built in filter and there is only one wire going into it , but with my eyesight i cant afford to pull wires about so could you get someone out to see to it and i will have to pay is that ok . Regards Mrs Magoo
