I went to Tygervalley shop on 3.2.2021 because on whatsapp call I could not hear ph ringing or the person when they answered. The gentleman was polite and worked on it and gave it to me. I could not hear any difference in the noisey shop and when I came home there was no difference.On the 11.2.2021 I was at the audiologist and asked the receptionist if she new anything about cell phones.She googled it and in 10 minutes it was fixed. I paid R160.00 to vodacom and that is a lot of money to a 85 year old. Do you give your people sufficient training
