Ban vodacom

After nearly 3 months Vodacom sends a technician to my house only to tell me they found the problem om their side and it will be fixed 30 mins later, 24 hours later still not fixed technician has been ignoring my calls letting it go to voicemail. Vodacom has still not refunded me the extra money they so willingly took from my account, just anotjer dissapointed customer vodacom does not care about.
