False advertising and bad customer service from Mobilepro

i bought mobileproG7 smar****ch fitness black(barcode:***54) and it was delivered on the 28th june 2021, the main reason i purchased the watch on takealot it was advertised that it can answer calls. only to find out that it only has call noification and i started a whatsapp communication with mobile pro on the 29th of June 2021 on their support number *** which was on the box and the person i was chatting to escalated the issue to the manager(Gugulethu) and told that it was a typing era and i was promised to be given a new watch that answers calls instead of them sending me a courier i opted to go their offices to go and exchange the watch to the one that answers calls, they told me to alert them when i come which i did and we agreed that i will be at their offices on the 2nd of july 2021, i must pick a colour which i chose black and i was told that only pink colour left and i said its fine i will take it. i had already prepare for transport to take me to their offices only to receive a call from Gugulethu at 8:57 am saying that the replacement watch is faulty(it has battery issues) and i must just return the watch to takealot for refund and i dont want a refund i want the watch that answers calls. here is the address that i was suppose to go unit B3 The studio, 6 Ateljee Street Randparkridge Ext 37, Johannesburg,2157. Gugulethu refused to give me a watch that answers calls as per takealot advert.
