Non-delivery by RAM

I have been waiting for a package for a week (since last Tuesday). Today the RAM courier arrived at my workplace, I went out to meet him and he was unable to hand over the package as the wrong waybill had been attached to the package. He told me that it might be delivered tomorrow but it would depend on when the waybill issue could be sorted out. This is completely unacceptable - this is RAM's mistake and something they need to sort out. Trying to get through to the call centre since the non-delivery has been futile. It's been a week for something which should have been delivered within 24 hours. Will I ever receive this package?
