Disappointed client

I went to sanlam on Tuesday to do the 2 pots emergency withdrawal on my provided funds they told me that it was successful but I did receive any sms to show that it was successful for 2 days ,I end up calling them because when for follow up, surprising whe I call them they tell me that they are very sorry it was unsuccessful due to 1 missing digit from my contact number but when I check on self service my contacts numbers are correct I don't understand at all, and also my question is that what if I didn't call them for follow-up I would have wanted for the funds that I won't receive I am so disappointed as am facing financial difficulties at the moment
