No service delivery AND assisting in refunding me

Hi all, I signed up with Vumatel and Openweb in September 2018, in January 2019 they were still not able to activate the service and played the blame game happily taking my money every month. I cancelled the debit order, contract and returned their equipment in January, requesting a refund. For months it has been a case of we will get back to you even now on my request to refund me.
