Transfers not Allocated automatically

Every Single time I do a transfer into my daughter's Lunchcard, I have to follow up after more than a week as the money never gets allocated, and YES, I am using the correct reference. I have complained and every time they say that the problem lies with the tuck shop owner and they will sort it out and it would not be a problem again. I deal with Lunchcard and I expect them to sort out any problems with the tuck shop owners then. If I forget to follow up then that money will most probably never get allocated. This is more of a hassle than convenient at this stage.
