terrible service

i have been trying to cancel my fibre service since july 2020,Our business has moved locations during the lockdown period, I then phoned in to get my fibre line moved to our new premises. I was told there is no fibre access in the area and that I can cancel the fibre line. I sent in all neccesary documents ,I dont get replies, I have phoned as well as emailed on countless occasions, no updates no communication nothing, I am still being billed for the service every month, I have been a custromer with vodacom for more than 25 years I cannot believe this service or actually the lack of service. I was contacted by a lady, to rate the service. I told her my true feelings about Vodacom. She assured me that somebody will contact me, three weeks later, STILL NOTHING.
