Disgusting Service

I ordered a cell phone online on the 16th of February, when i inquired i was told it will be delivered by DSV courier, since last week Monday i have been sent from pillar to post by DSV and Mondo, DSV first said my device was posed by MTN but when i call MTN they say everything is in order on their side, later in the week DSV said i should contact MTN to update my details and my device is at MTN warehouse, i called Mondo again and they said they sent DSV an email to confirm that they should deliver my phone but they say they can't since its at MTN warehouse.

On Monday the 28th of Feb i ordered another device and now i told the same story again, i should contact MTN.

Today, the 2nd of March I made 3 calls to DSV but I got told I should contact MTN, but Mondo says they asked DSV to release my order, i have had a contract with MTN for over 12yrs, but I have never received such disgusting service as this.

I don't even know who to call anymore as I even called MTN directly on the 28th and they promised to call DSV.
