Bad Service

Around 08:50 my account was placed on hold and the is no reason provided I only found out when I wanted to buy some gas at the gas station. I called there and there and I was advised that my matter has been escalated to the relevant department and I will get a call soon. Up until now no feedback, I am so stranded as I can't shop or do anything since the funds on that account. It's the second they do this and last time they promised it will never happen again. Am so frustrated now as today is wasted and I couldn't get anything done. Am definitely leaving them once they sort this out.
