Technical issues with the WiFi connectivity

I have a contract with Vodacom for fibre internet connectivity. I have been without internet connectivity since last week Thursday. I recieved a call today at 10:05 and iPad network issues as the technician could not hear me., I tri d calling back but the phone went to customer care. This same technician called and hung up after 28 seconds, only for them to send me an email saying they have been trying to get hold of me and that I should respond to the email. I immediately phoned the customer care line and responded to the email and included an alternative number, but there was no confirmation of receipt of that email, there was not callback from their side.

I am studying and my course runs online. Everyday since last week Friday I had to buy data to stay up to date, while I had already paid for the WiFi. This is frustrating, a waste of my time, and my money that I will not be reimbursed!! I request that Vodacom take their customers more seriously and respond to my issue promptly. This is really unacceptable!!!
