VOX turns off my internet line

I am dissappointed with VOX telecom. At first i decided to sign up with Vox which took almost a month just to get your wifi up and running and the router took just as long. I changed my password on my router and this is where i regret it as the Mikcrotik router is very complicated and i could not change the password and the router went offline . Eventually after a few days where i kept struggling to get through to the technical department as i was always caller 38 in the line we managed to get help from a salesman in PE. We were told that a tech will be sent out without warning that it will cost R1500.00 call out fee. As the the tech eventually arrived on a Sunday which i think is not appropriate..he advised about the call out fee and he fixed the router in five minutes!!this couldnof been avoided id the call in services wasnt so bad where i could of been assisted on the phone to fix the password of the router. After what i have been through just to get internet with VOX, they decided to stop our internet line and ordered us to pay the call out fee in full. Now we got a final demand. VOX has forgotten how terible there services are but they are surely very fast to stop your line due to there communicatikn errors before getting the router sorted out. Ive dexided to leave VOX as they do not care much about service. Just the money in the bank as i see it
