On 8th March I called EE because I could not access my data on EE website I was told I would have unlimited data as there was general technical issue. I received a bill on the 11th March of a £53 my monthly bill is £15.79. I called on 15th March asking why I was charged so much. I was told by a male operator that I selected a £ 20 monthly add on. I do not recall selecting this as a monthly charge on top of the £15.79 i already pay every month. I was told due to the high amount and the bill was already produced I will be refunded the £20in April. On 11th April the new bill appeared with £8.78 charge but no £20 refund.
