Refund

In December 2022, I contacted rain for their services as I was going to work from home,rain delivered a wifi that was not connecting were some days I contacted rain the next day after delivery and asked them what is happening because the wifi is not working they then told me they are struggling with connection and it has been a month switch bothered me so much why they would continue providing services that ain't working at all,I then requested for them to come collect their product and refund me back till this day I am still calling rain to request for my refund and they keep telling me it is going to be process it has been 6 months yet I have not received my refund they now hang up my calls on me when I call to ask for my money
