Rewardsco and DSV unreliable liers

So I was contacted early in April 2024 regarding the upgrade on my MTN Contract, which I then decided to renew my contract and get a new handset. This was finalized on the 7th of April at which time I was advised that DSV will get in contact with me regarding the delivery of my new handset.

DSV then contacted me and infoed that the handset will be delivered the following Monday between 9 and 11am. I'm a sales rep and can not afford to sit at the office the whole day waiting for a cellphone delivery which I explained to the consultant. They assured me that they will definitely deliver on time. Needless to say the driver arrived at 16:15 that afternoon and then they could not verify my biometric due to a faulty machine. They then turned around and left with my handset..

Long story short, it's the 21st of May and I still have not received my new upgraded handset that I have already started paying for. Almost 2 months and this only for an upgrade.. I have 2 contracts with MTN so it's not a new contract and they still treat you like you mean absolutely nothing. DSV is the most unreliable and unprofessional people ever and always drops your calls and never gets back to you as promised. Every time I contact Rewardsco they set a new date for delivery but this just never happens, they don't even contact you regarding the delivery. I'm going to a MTN shop today to try and resolve it with them directly as all the rest are just a bunch of liers.
