DSV long call waiting

I have upgraded with MTN they told me my upgrade was finalized and I can contact the courier company DSV at *** to track my parcel. I called the number and selected option 4 to speak to switch board operator and told her I need to track a MTN parcel she did put me through and I was assisted fast. The person told me that DSV need to confirm and appointment with me he will be putting me through to another department this department however never picks up the call at first try I holded 15min before deciding to drop the call and try again. Second try I told the helpful department (one that tells me that DSV need to arrange an appointment they will put me through to the relevant department) that I want a direct number cause I have been on hold with the (arrange an appointment department) already and they dont answer. He did tell me that they are aware and other people also complained about this. Unfortunately they dont have an direct numbers so I will have to hold until my call is answered I am now busy with the second attempt to reach this useless department and already 20min and no one has answered my call... Now how much of my airtime must I waste before I can atleast talk to someone to arrange a appointment???

Cant believe MTN with such great service use people like DSV that destroy their reputation completely this is not customer service wake up people...
