Before buying the Galaxy S7 I asked 2 separate online customer advisers if the S7 worked with wifi calling at this time and they both assured me that it did and tried very hard to get me to sign up through each of them but I said I was going to think about it. The next day I decided to buy online and collect at my local store.Once at the store I asked the staff member to confirm the s7 will work with wifi calling now and he also assured me that it did, great can you set the phone up so it will work for me when I get home. Before leaving the store I again asked that the phone had been set to work with wifi calling and he said it had.Once home I discovered that it had no option for wifi calling so I called customer services and they said the S7 does not work with wifi calling.So 3 different Vodafone staff members either gave wrong information or lied to me to get a sale.Back at the store was a nightmare...the same staff member ( assistant manager) thought it was acceptable to shout at me at the top of his voice in front of other customers that he hadn't told me it would work with wifi calling, after reminding him of our earlier conversation when I bought the phone he again shouted in front of a shop full of customers ..WHO ON EARTH BUYS A PHONE WITHOUT KNOWING HOW IT WORKS!! very intimidating..I left the store and called customer services to complain but they wasn't interested saying they could only put it on my notes so I wrote a letter and posted it to the address on their website recorded delivery but they didn't even acknowledge my letter or reply. After making several requests I finally received a returns bag and have now cancelled my contract and sent their phone back.NEVER NEVER NEVER AGAIN WILL I USE VODAFONE AND I HOPE IF YOU'RE READING THIS VODAFONE YOU SHOULD HANG YOUR HEADS IN SHAME .......IF YOU CAN BE BOTHERED THAT IS.
