Rain refund

After joining rain and delivery of my sim I had to cancel the next day due to no coverage. Which was on the 3 of December 2020. There was no penalty as it was the day after I got the rain sim. Cancellation was done and refund was to be paid by rain to me within 7 working days. I phoned them and double checked the information on banking details for refund. After numerous calls to support and reconfirming information, again, to date my money was not paid back. Every time i phone them it costs me money in airtime. Each call lasts about 8.5 to 10 minutes according to my call log. Today is the 29th of January 2021. During this week an email was sent to me from rain to say that i, the client, must check my bank statements as payment was made. Just have to add that you can not mail them, they have to mail you with a reply link for you to be able to contact them through mail. I did so and no refund payment from them reflected on statements. I did send them a mail with the statements as proof. I also called them again to confirm if they did receive the mail. They confirmed. This morning I phoned them again asking when refund payment will be done. Answer: they are processing the payment and i must stay on the line as the operator checks for me. Needless to say, airtime ran out and call got disconnected. Nearly 2 months and I am still waiting for R470. Rain is a big company and I am sure they have a lot of subscribers. They advertise on a lot of websites. Why so difficult then to pay back such a small amount and why is it taking them so long. And why did they lie saying refund payment was done and then after proof was sent that it was not paid, now they are processing? A company as big as them and lying to the client. Decide for yourself it they are trustworthy. I would not recommend them on the basis of that.
