Refusal to increase spend limit

Honestly disgusted and appauled by your lack of customer service. I have to increase my mothers spend limit on her behalf but you wont let me. Yes policies etc... what you dont understand is that my mother is unable to speak as she has had chemo therapy. I have all her details but you refuse to assist me in this matter? I am scared that she has an emergency and she needs to message someone to help her or give someone a missed call whatever. I want to make something very clear... if she indeed has an emergency and cant use her phone I will personally hold Cell C accountable! I do understand you have policies to follow but this is a matter which should fall outside of those policies! You must better hope and pray that nothing happens!
