Poor service

On the 6th January I registered at Damelin and received proof of registration on the 12th of January. I received an email stating that I would receive my study material within 21 days but till today I have received nothing, every time I call I get an excuse. One of them being there's no waybill numbers from the delivery company to systems being down. I have spoken to Yolanda twice and every day she promise to get back to me. The first time I spoke to her was on the 10 of January and I spoke to her again on the 16th of January. I'm really frustrated since this is the first time I will be studying at Damelin.
