Bad communication and training of employees

Recently stored goods at Table View storage, removed them on the second last working day 31st July. To date i still have not received my deposit back. Spoke to Lauren who said it would be paid in by the Friday 8th August, no payments, then it was the weekend, then it was the following weekend and to date no monies have been paid into my account. Why do your employees tell clients that they money will be paid it is clearly IS NOT paid. I find it irritating to say the least that firstly you are sitting earning interest on the deposits that you are with holding and we as the client are waiting for our money to be returned. TOTAL BAD SERVICE ON STORE-AGE SIDE..It was not that they did not know i was moving out or anything this was stated two weeks prior so there is no reason why the money is not returned.
