Unhappy customer

I signed up with Rain in August 2021. The consultant that assisted me informed me that "I am not signing a contract where they (Rain) will be debiting my account, but I will pay the R250 as an when I need their services."

1. They don't have coverage in Soshanguve and they had told me they do. Which means my R250 went to waste.

2. They debited my account in September, and twice now in November.

3. I have been sending them emails telling them I am no longer interested in their services, and that they should refund me, using the same email address I used when I signed up with them. an someone please share a telephone number I can call or an alternative number.

All I want is for them to refund me the money they debited my account with in September and November
