NM096526: R1200 Refund - Bad Customer service

My wife had an account with vodacom and fell behind with her payments, the cellphone contract was handed over to legal and contract terminated. My wife made an arrangement to pay the overdue amount, she found out November 2019 that she has over paid and that there is an amount of about R1200 due to her and given ***

On the 22 November 2019 she was advised to submit 6 months proof of payment , which was done but since then, everytime she calls vodacom or tweet them, she is promised someone will contact her but no follow through is done.

Until today, vodacom has never made contact or provided a contact number where my wife can contact them with.
