*******, *********** or just plain spiteful?

After paying installation fee and receiving router July 2023. Web Africa came back and said they couldn't assist me and arranged to collect the router from me and refund my installation fee. Nobody collected the router. December, they realized they don't have the router, and collected it in January, It was still in the packaging they sent it in. 25 January they sent me an invoice for the router. I did contact Ovena and the legal team who I dealt with regarding the collection of the router, but no reply. 1 Feb they debited my account for the router. So now Web Africa has the router and I paid for it, that's *******. I have logged a dispute with my bank, and they refunded me. I need Web Africa to come into contact with me to fix all of this as they have received their router, and still owe me the installation fee, but they charge me for the router.
