So I moved to 02 in October having been with Vodafone for over 10 years. This is the worst company in terms of customer service. 02 took my direct debit every month and sent me a letter saying I had not paid. Spoke to the rudest woman in history called Kaylnne. She refused to help then after a bit of an argument she decided to remove my sim from the network....she basically sabotaged my phone. I use this phone for business and have now lost work and money solely due to Kaylnne. I have read that this illegal so will be following legal route to get this resolved. Please please do not use 02 otherwise they will ruin you and your business.
