WebAfrica is refusing to refund me for a cancelled service

In October 2024, I signed up for Vumatel fibre and a few days later, their team of installers came and required 2 times the amount of money set up my wifi. Webfrica claimed that I will get free installation, but after making a payment, I received their emails where they told me that I will be charged for extra wiring. I paid R399 for my Vumatel fibre, but the technicians required R925 to set up my services. I decided to cancel the service. At first, a Webafrica agent sent me to Vumatel for my refund, but another Webafrica agent promised me a refund within 10-14 days.

It's been 3 months and I am still waiting for my refund. Everytime I make an enquiry, I am promised payment within a few days but I am still waiting for my money.

I need help. Clearly Webafrica has no intention of refunding me. This is unfair and unjust. They were quick to deduct my account, but take time to refund me.

Please help.
