NO LETTERS NO EMAILS NO NOTHING. i tried on 3 ocasssions to cancel the contract. Originally paying £12 a month then all of a sudden it goes to £20 a month. No warning, no letter or email to say this was happening. I only ever use this phone as an emergency so it hardly gets used. I contacted their customer service which i have to say its the worst customer service to exist. First person I spoke to said you have to give 28 days notice. I said thats fine , i am giving you the notice now. he said after 28 days it will be cancelled. 2 months later, im still being charged. I contact them a second time. the chap said the previous agent did not cancel it. he will do it now for me. GREAT i thought. anyways next month same thing. I phone customer service who i get this stupid women who was like " i can see you do not use your phone much, not a fan of technology hahaha" how unprofessional. I told her enough is enough this is 3rd time I am phoning to cancel. They have had 3 months notice not just 28 days. I told her i am cancelling the direct debit and expect to recipient confirmation in the post it has been cancelled. 3 1/2 months passed no calls, no letters no emails. Then today I got a call from a debt recovery agent. Vodafone have sent it to debt collectors. what a joke. STAY CLEAR OF VODAFONE. i will never ever deal or associate with this rubbish again.
