Literally the worst courier company in South Africa

I honestly don't understand how this company got a contract from Takealot to be one of their couriers, they are absolutely useless. I have a big, expensive package that was scheduled to be delivered on Friday 28 December 2018 and guess what, it never came. No explanation, no feedback, it just didn't come. On Saturday I received an SMS from Takelot (not even the couriers themselves) that delivery is rescheduled for Monday. Now I have to wait the whole weekend and pray that it actually comes on Monday. If I read the other reviews I doubt if it will ever come. I am beginning to think that they stole the package since it is that expensive and big, I am seriously considering opening a case at SAPS for theft. If I don't receive the package on Monday I will be driving to their warehouse in Pretoria to pick it up myself, if the package isn't there I will call the police. If this is the way they do their jobs, they don't deserve to be in business.
