THEY DON'T PHONE BACK

My mother borrowed me money for food and was transferred into my account this morning. I went to buy meat and card was declined. The money was transferred to reflect immediately and I did not have enough money on my phone to speak to the Call Centre and explained this to the lady when she answered. She then told me they will phone me back and confirmed my tel number. Needless to say I did not receive any call back and am stuck with no money or any food for the weekend. I am not only disgusted with the service from the call centre but also with the person who clearly understood that I was desperate and needed her help.
