I need a proof of purchase to give to mtn who I took my contract out with and pay every month

Got a phone on contract in March 2021 which I upgraded through retentions ,the phone is a Huawei p40 lite, this phone is now heating up to the point where it is burning my hands, so I go into the Mtn store in gateway and they cannot find my proof of purchase but have my details of the contract on their system ilula.

The assistant in store says because I took it through retentions only they will have access to it (like they are a different company) no ownership and accountability. She then takes 30 minutes to get through to retentions who says they will send it to my email address which is never done its been almost 2 weeks...

I make numerous calls to 135 who try to pass me to retentions and after 30 minutes of holding the calls cuts, when I ask to speak to the manager the call cuts.

Mtn this is a health and safety issue and your service is pathetic, you guys keep passing the buck and don't help customers.

Now I want to cancel my contract and lay a formal complaint to the ombudsman.

You are putting my life at risk using this phone that is overheating and you won't help me in store and I cannot get through to retentions to get my proof of purchase.

Please help me, this is frustrating.

How do I log a ceo complaint to 14th Avenue.

Mtn sucks

I am going to stop paying my account!

You guys upset and frustrate loyal customers.
