DSTV Change of Ownership Service - Non Existant

I completed the change of ownership from my deceased father to my mother on the 14th of May 2021, sent through the requested documents and now nothing. I have sent a number of emails to DSTV Help with no success. Tried the online chat, I was told it would take 2 hours for the change of ownership to go through and I would receive an email for the amount that must be paid to switch the DSTV back on.

NOTHING. Spoke to the call centre and they cannot help me to see what has happened with the Change of Ownership.

My mother has now been without her DSTV since the 14th of May 2021. What must I do to get a response from DSTV?

Many thanks Heather
