Bad service ever

A call center agent called and offerd me a contract a accepted.i asked my to keep my existing cell c prepaid number.It took them over a week to change it to contract.the phone was delivered.i only had it for a day it was faulty.they collected it..it took them 2weeks to send a new phone to me.Finally it was deliverd and it was a wrong model,not was I was offered and what we agreed upon.so disappointed really.
