a month without a phone

Last week I wrote a report and got a responce with a referrence number and samsung centre said they will call me to sort my problem. They haven't called!!! I call them myself EVERYDAY and they tell me the same thing they have been telling me for the past weeks \we will be receiving the parts this week\". Bare in mind that I took in my phone for repairs on the 11th Jan and they said it will only take 3-5 working days. Today is the 9th FEB!!. Samsung is failing with this bad service. Youv lost me as your customer! The amount of disrespect, dishonesty makes me sick!!! I need my phone back!"
