Shop very busy, assistant dealing with 3 people at once. I asked for 4 - 8 GB data, after over an hour 'being served' I had to leave because I had to pick up children from school. Shop is 30 miles from my home. When I received my paperwork from Vodafone I realised that I had been sold 16GB data. Every time I rang the shop I got 10 minutes of music then cut off, cost extra £4 each call. Found a free phone customer service number and was told that they would email the manager to contact me. I did this 3 times over 2 weeks but no email. 4 more calls to the shop and still no answer. I have been told by customer service that as they're a retailer they don't give a 14 day cooling off period.Had I gone next door to the Vodafone shop I would have had 30 days to change my mind. Absolutely no help at all. I feel that the assistant recommended this package knowing that they wouldn't allow any changes and he would get a bigger commission. I am stuck with this for 2 years! Do not use these rip off merchants.
