Horrible customer service!

I took up a contract with Vodacom on the 15/01/2019, three weeks later the device began giving me network problems. Half of the time it shows "no service" on the top left corner of the screen. I contacted Vodacom customer care several times to report this and try to resolve the issue with no luck in the end. I was then instructed to take it to a Vodacom shop, who were also of no assistance to me because the device was not purchased from their store.

So now I am stuck with a phone that has no network, and Vodacom continues to debit my account monthly.

VERY UNPLEASANT CUSTOMER SERVICE!!!!!
