MTN refuses to release my refund due incompetence

Ordered a home wifi package on 8th May 2024 and paid the upfront fee. Delivery was an issue as the biometrics system didnt work. After 2 attempts, everything went silent. I contacted 7 different numbers before the last person told me my contract was cancelled. Short story is that since 8th May to current, ive been given the run around by *********** staff. I keep getting told my credit is reflecting on my profile and i need to request a refund..ive done 3 requests so far and still nothing. These call centre agents make notes on their system but do not inform the customer. Been to the store Pinecrest Mall, Pinetown which has also been a complete waste of my time. Each dept passes me on to a different one and each timw the story changes. I need the damn refund so i can go to a more reliable service provider where hopefully their staff is better trained.
