As usual they nerver seem to disappoint, the service is horrible,they never have answers, i am paying for things i never authorised when i asl them how or why? i get a "i don't know" answer!!!! this is ridiculous wouldn't recommend anyone to take out a contract with them!! the goal post is always moved when it comes to the ending of contracts!! this is nonsense!!!! please note they will make you hold the line for 30 minutes while they "investigate" then come back and say we cant see anything mam!!! aggggg
