Poor Service VODACOM and RAM

I upgraded one of my lines.

Vodacom with RAM was fast to deliver new device which was unfortunately the wrong device. It was delivered on the 28th of December 2022. I contacted them on the 29th To rectify the matter. Vodacom informed me that RAM need to collect the device and we will need to cancel the upgrade and redo it again to get the device rectified.

The collection was booked with RAM on the 29th of November 2022 with Tracking Number: V1P***. RAM has failed to collect to date they make appointments and do not pitch up to collect. It is now taking them 9 days to collect and still they fail to collect. I have been phoning continuously every day RAM being told by RAM the courier is underway to me and they never arrive or inform me of any changes I truly don't know if they were on their way from Cape town they should have arrived by now. I now asked Vodacom call center to have a manager to contact me in the hope of resolving the matter.

Who at Vodacom can I contact to sort out this poor service delivery. Alternatively where can I find suitable legal advice to cancel all my contracts with Vodacom if they do not resolve my issues today. I mean I am paying for services which is not up to standard.

Kindly assist.
