Finally managed to cancel my monthly contract for the third time in July 2018 after first cancellation on 4th of January 2018 which hasn’t gone through because of Vodafone error and second attempt in March. Been taking for ages (2 years contract which finished in December 2017) even with screen shots of the first 2 cancellations that they completely ignored but would have been useful in a court case should they have not sorted this out. If anyone reading this wants to cancel their contract with Vodafone I advise you to take screen shots or record the cancellation confirmation, name of advisor and reference numbers as they will not do it from the first attempt, they will still try to take money from your bank account and charge you. Definitely will not use Vodafone again!
