Vodashop not explaining things if phone is faulty straight out if box you will have to go the extra mile yourself .. or wait forever for them to do it ...

Bought a j2 core yesterday cash at vodashop east rand mall 20 Nov 2018 ... on the 21 nov 2018 want to put it on charge and it doesn't want to charge .. tried a few other chargers same problem.. phoned them and explained the phone is less about 24 hour old and 1 st time doesn't want to charge if I come in now do they have another handset similar colour to exchange with ... he michael when to check and came back said yes they do . I said I will be there ist now . Came there ... then they the manager said the phone must be booked in and it takes 7 working days ... because and I signed a paper ... the lady that helped us the previous day said we are signing to state the box is sealed when received . .. nothing else .... why not explain to me when I buy or over the phone when I phone to state my problem .. instead the sales guy went to check that they have a similar phone a colour ... .... this is my daughter's first phone she bought with her own money and I am not to happy with them not giving proper info and waisting my time cause I must drive up and down .... now I am taking it to customer care myself ... could they not explain the first time that if a phone is faulty straight out of the box that I am going to have to go a few extra miles even if it's not my fault ...
