Unhappy paying customer

This is one of the worst internet service providers I have dealt with. I phoned Rain before taking their internet and I explained to them where I am staying and That I am surrounded by trees. They told me that trees aren't a factor when it comes to their services. They also told me that I am surrounded by towers so signal wouldn't be a problem. So I decided I'll l go with the Rain 5g for R499. The moment I said yes they deducted R500 from my account. The router arrived and I've plugged it in. Since I plugged it in I never had 5g coverage. I couldn't connect more than 2 devices. 5 days after that the signal disappeared. I phoned Rain and they came with lots of excuses and said I should rebooth the Router. I did that several times still so signal. I phoned Rain several times and each time they had a different excuse. The last person told me thay the there's too many trees around and I am very far from the towers- the exact things I asked them when I was gathering information on Rain. I canceled the contract end February and still till this day I am awaiting my refund. They even deducted money again from my account after I canceled the contract months ago. I really wouldn't recommend this service to anyone. This is a really bad service and they are so unhelpful. I've been phoning and emailing them without getting answered.
