I find myself getting increasingly disgruntled with giffgaff and am as a result reminded of a once perfect IP Service provider called Madasafish!
I have recently changed goodie bags from the £25 to the £20 and ever since doing so my internet searching & loading has been frustratingly slooooooooooooooooooooooooooow!
I appreciate that you are experiencing issues with Chrome but I have installed other search engines and the service is equally pants!
I have performed deep cleans, performed virus checks etc, etc, but it still remains pants!
The only consistency is awful internet service and constant crashing without warning! Please do yourselves a favour and do not go the same way as Madasafish.
