Poor service

I am heavily dissapointed in Vumatel/SADV service. I made an arrangement with the ISP to debit my account on tbr 25th of every month...on the 20th of December 2023 my account was debited. Within 5 days (25 Dec 2023) My Wifi was disconnected and I was told that I need to pay again. This means i paid monthly subcription only to have access to tbe wifi for 5 days (this is unfair). I since requested to cancel my subscription instead with them, however Iam being told that they referring my matter to another department, today marks excatly 3 weeks of waiting to be assisted and still I do not have any connection to date. This ISP is taking me for a long ride. This is a huge inconvienince and no one from their departments is willing to assist.
