Telkom Vangate bad service

This is my first time having a contract with Telkom and I'm not a happy client. I opened up two contracts on Sunday ( 20/01/2019) Huawei P smart. And on Wednesday I took it back because there was no finger print ID on the phone. Out of box default and Telkom refused to give me a new phone as I took it back before 7 days. They were very unhelpful at Vangate Telkom. I have to now wait up to 21 days for a brand new phone I didn't even use to come back from technicians whereas I could of gotten a new phone as it's a manufacturer fault.
