Very bad service and robbing people their money

Theie service runs for 30 days, on the 20th of December I paid and I couldn't connect, which I had to send them a WhatsApp message at 18:14 and managed to get a text back from Liezel at 19:36 since one cannot call them and it Sucks. You logged my called and advised that they will send a technician in 24hours, which did not come through and they will start continue the 30 days meanwhile I paid for the service that I'm not using. Vumatel is ripping us off, how can you work with customers that cannot call or email you. Their emails are " noreply" only WhatsApp. Now I want to query that I paid and I don't have wi-fi but I cannot speak to anyone except a robot that only gives you options that are not related to what you are querying.
