Useless courier , bad service , lack of efficiency

Ram couriers is one of the useless courier service I have ever come across , my parcel was out for delivery on Tuesday, I rescheduled for Thursday now they didn't delivers Thursday now my parcel is stuck at one their hub, pathetic service I am not sure why dstv has to use them for delivery, they lack sense or urgency and they use peak time as an excuse that's ******* I need my parcel
