I received very bad service when I went to return my phone. The staff in the shop were very rude and very obnoxious. I'm not sure whether they understand what customer service is. A particular guy call Ahhmer was extremely rude and to be honest I don't think Carphone Warehouse or anywhere that would like to deliver excellent customer service should have someone like him working for them. I wanted advice on how to return my phone and Ahhmer told me to be quiet so he could hurry up and get me out of the way. He wasn't interested in helping me with any queries and didn't seem to care whether the store kept my services or not - you do not speak to customers like that under any circumstances.
