Appalling service from Ram Couriers

I have a parcel from Vodacom that is being delivered by Ram Couriers. I received an email from Ram Couriers that my parcel would be delivered on Friday. Waited the whole day and no parcel arrived. Tracked my parcel on the Ram website only to discover that there is an entry that there was a failed delivery because they tried to contact me and my phone was on voicemail which is not true. I received another email this morning saying that tehy would deliver again. The delivery guys came to the delivery address and they were told by a colleague of mine that I was just a few meters away in another building. They made no attempt to contact me to say that they have arrived with my parcel. I then phoned Ram customer service and was told that there an entry already that they were not able to deliver to me. I asked the lady that I spoke me to please ask the delivery guys to contact me because they should still be around. Have not heard from them . Extremely disappointed with the service because they seem to really not care about communicating with people and ensuring that parcels get delivered. Appalling service and it’s a shame that Vodacom has to deal with such a terrible Courier company.
