Vodacom Chatsworth bad service again

Hi Vodacom shop Chatsworth center has the worst customer service and the worst consultants.

This is the second time I am having issue with the store. The first time my phone broke and I was paying insurance but after some time the store said the insurance is rejected. I sorted out that issue myself with customer service and I got a new phone.

This time I upgraded my contract and the LG rep (Justin) at the store gave me wrong specs for the phone LG8S thinq. He said the camera is 32, 18 and 8 but it's actually 12, 12 and 8. He said it had better camera than Huawei P30 and he said we can even take pictures underwater. I am very unhappy this phone and I want to return it. The store won't take it back eventhough it's within the 14 day return period and they say there is no return policy eventhough another customer just returned the same phone with a similar issue.

Please assist
