Pathetic, bad service

I am so disappointed at bad service from Atterbury branch! I went there to get my new iPhone sorted and discovered my number was disconnected. I was overseas but forgot to send 2 messages and they charged me for a new sim and and no. The person sent a request to retain my number, promised to phone me with result, but nothing happened! I phoned their shop, a lady answered, said she would phone me back as she was with a client - nothing happened. The technical person installed my WhatsApp, told me it would work when I came home, but it didn’t work - I also paid for it, so I am extremely disappointed. I will now have to contact ALL my contacts, bank, medical practitioners and anyone else who has my old telephone number - all at my own cost. I would not recommend them to anybody.
