Disappointing Service from Rain

I app**** for a 24 hours SIM card in August 2022. Rain didn't inform me I have to cancel the 19th hour SIM card. Rain was charging me for both SIM cards. On the 12th of September 2022, I started having problems with Rain's internet. It was working at night only but it was unstable. I have to buy data for during the day. I informed Rain about my problem but they didn't attend my problem by only deducted R729 on the 1st of October 2022, from my bank account. The only time Rain communicate with you is debitibg your bank account.They deducted again on the 1st of December 2022 and twice on 31st of December 2022. Raib's app is sating, I am owing them R663.31. Other internet service providers are not stupid because they have branches. I respected Rain before what happened to me but now, I feel otherwise.
