Unfair practice and *****

So rain decided they are going to credit themselves with my funds. Since the beginning of the year I’ve been having connectivity issues, I raised with rain, they gave me excuses about the towers. In the month of May I logged a ticket with them, they charged me for not calling, I then called and asked to speak with a manager, they asked Tess or someone by that name whom “is a manager “ apologised for the error charge, she asked when it’s suitable for me to pay the subscription, I said the 20th but I know you don’t offer that date, she said “ no I can arrange for your account to be debited on the 20th”. They did debit my account on the date but now to my surprise they debit again month end, when I asked why, they said it’s for the previous month 👀 which month…now my invoice keeps showing a credit amount from the 20th May which they don’t want to refund or credit for the new month. Not only is the products misleading (which is against the consumer protection law) but also they are committing ***** 😳. Right now none of them will call me nor will they fix the error, which is fine, I’m collecting all the invoices, reference numbers and names.
