Very Disappointed client

Very bad service I purchased a Samsung A3 core im happy with the phone but you guys don't put the part in to open the phones sim card this is unreal and to top it off you advertise a sim card for vodacom with free data for one year but leave out every last detail, don't rica the sim, dont even explain anything that we need to recharge R29 airtime per month to have it activated when I call in as well your customer care sends all wrong info on the email.
