STAFF NEED CUSTOMER SERVICE TRAINING

Bought a pair of shoes, wore it once & the buckle broke. I took it back to N1 City & asked if they could replace it with the same size. They didn't have size 4 but checked the other branches & phoned Cavendish Square right in front of me & asked them to keep it for me as I would be coming to collect it straight after work. Cavendish confirmed they would keep it. However, when I arrived & gave them my name, they said that nothing was being kept for me & that no-one from N1 had phoned them. I asked them to please check & to phone N1 to confirm. They kept me waiting for 45min and then told me that they phoned N1 & N1 had confirmed no-one had phoned Cavendish. So I phoned N1 & spoke to the lady who assisted me that afternoon & she said she would phone Cavendish to see what was going on. After I told the assistant at Cavendish that the lady who helped me at N1 would be phoning them now, he went to the back & within a minute or two he brought me the shoe I was looking for in size 4, which made me think he was lying & deliberately kept me waiting. I don't have an account with any other store but if I receive this level of service again, I will definitely close my account & shop elsewhere.
