Horrible service received

I have been battling with Ram since Monday, I received a message on Monday to let me know my parcel was handed over to them by Vodacom, I Immediately phoned to let them know not to deliver on Tuesday as I am not available and was told a note will be left on the system for them by the agent, to my surprise they tried to deliver on Tuesday and it was returned, I then phoned again and was told they will reschedule for Friday delivery, this morning, Wednesday I receive a message to say it is out for delivery, I have tried the whole day to get hold of them to no avail, I just want to find out what time the driver will arrive, and if this now gets marked as undeliverable again, this parcel will be sent back to Vodacom and I will be liable for payment, but RAM does not assist in any way, when I contact them on WhatsApp I get cut off halfway through my chat, the call centre says they cannot contact the driver or hub????? the hub does not answer their phone, so what am I to do??? as clearly you can't reach anyone actually dealing with the parcel or driver, and the so called notes made does not get read or followed by anyone.
