No decent service but you demand monies

After having made a complaint to Hello Peter on 25th January 2023 regarding non cancellation of my data contract and the fact that Sonny from networks advised that vodacom would not charge me as there was no signal in the area, vodacom rep**** on hello peter advising that they would get back to me within 24 hours. Guess what? Nobody bothered to come back to me!!!! Suddenly i receive a letter of demand from vodacom yesterday demanding that i pay over R400 to them!!!! I never had signal from inception. Your representative store at Oakfields Benoni didnt bother to check availability of signal when i purchased the data contract!!! Now you want to demand payment from me. Despite numerous emails to vodacom, numerous complaints to hello peter, you have done absolutely nothing to resolve this matter!!!! You cannot expect me to pay for a service you could not provide where i stay. I had to travel to where i could get signal before i could access the internet. Is this how you do business?????
