VODACOM - NO RESPONSE !!!

I renewed my contract at the Vodacom shop in Clearwater mall at the end of November 2019. After using it for only one month, the Samsung A70 started to overheat when using it for only 10 minutes, the battery drained in half a day and a glitch started to appear(the top tab constantly came down without even touching the phone).

As I am not in Johannesburg anymore, I took the cell phone to the Vodacom shop in my town. They told me that I needed the receipt from the day I took out the contract; however I did not have it. I then phoned the Vodacom shop in Clearwater Mall countless times requesting this receipt, however I was just told that they will email it to me but they never do. I've even received an email from Customer Care stating that they have phoned the Manager at Vodacom Clearwater, Esther, but I still have not received anything.

Vodacom will not fix my phone if I don't send in the receipt which they have. Now I am going to wait weeks, if not months, so that my brand new phone can be fixed. Currently I am paying for a phone I do not even have. Customer Care says they can't do anything about it and I've had no response from Vodacom Complaints Department after sending them emails. The Vodacom Complaints Department does not have a contact number. Here are all my Reference numbers:

• 0022YaF17RVUJDED • 00234aF1Y6QB43JH • EC-1YIC-23O1ZD • 0022YaF17RVUKCMB • 00234aF1Y6QB49E9 • EC-1YIH-2FWNF3 • EC-1YIH-2FWOY5 • EC-1YII-275UDA • EC-1YII-27MPTW • EC-1YII-27TRGJ • EC-1YII-275UDA • EC-1YII-27G08L • EC-1YII-27GZ5G • EC-1YII-28VW0C • EC-1YII-28VZYJ

What more must I do???
