Failure to provide a Proof of Purchase or Contract Documents.

I renewed my contract around October 2019, Had a bit of a run around before this could happen. Fast tracked to 2020 one of two devices upgraded my Samsung A30s goes totally dead on me all of a sudden, not charging or turning on and I had tried all troubleshoot options. Go to Samsung who advised I provide Proof of Purchase for the device or Contract copies. Moved houses in 2019 and cannot find any documents. Contacted Telkom in February via the Customer Care online support and called in, spoke to various people and departments with now joy. I go to a Telkom store for assistance but turned away (Yeah imagine that 21st Century yet a Telkom store cannot assist). It is now 1 month and 2 weeks into chasing around for a document to prove one simple thing. I am the owner of the device purchased from Telkom (Which btw is a contract). Yet somehow its such a challenge for Telkom to provide any information despite making monthly faithful payments towards the contract that their customer care and store cannot prove I am the owner...... I am at a total loss with this device financially and emotionally upset that this is the service you get for been a loyal 3 year customer with Telkom aka Hellkon
