Worst customer service

I placed an order (sim+router) on October 31,2023 and paid for it. It was was supposed to be delivered in 3-5 days but till today I haven't received my order. I work from home so internet service is a need, I needed a solution fast so I placed another order with a different service provider on Monday (6 Nov) and it was delivered on Tuesday and I am able to work from home. Yesterday I called rain to enquire about my order since there has been no update/ communication from them. The advise I received was the shocking, the lady said that order will be cancelled and my money will be credited to 'my rain acc' because they wont refund to my bank acc its past the 7days cooling period for cancellation. She said new order will be placed I have to pay again and it will be delivered in 3 days then the next debit order will go off my rain acc from the refund of the cancelled order. I laughed because how do u expect me to trust u and pay again when u haven't even delivered my 1st order. She finally decided to transfer me to cancelations where I spoke to another lady who said it has been escalated and I will be called back with feedback by COB yesterday. As expected no one called me so I called this morning and was advised that I will receive feedback by Monday latest (since it takes 24-48hrs). Clearly someone doesn't know their processes or even worse someone **** to me regarding the turn around time for feedback. I want nothing to do with Rain I just want my money back.
