Incredible online service Bad Bad bad BAD BAD BAd

On the 27 May 2019 at 05h15, I logged on to the incredible connection website to purchase a phone online, samsung A8 which was advertised for r5999, from 26 May 2019 till 31 May 2019. I struggled and contacted the customer care , they were unavailable. Ive tried from that time and decided to go to Incredible connection at Blue Route Mall to assist me with my online purchase. I got there after 9 and the teller treid to assis and went to call the manager, one of the other guys came and assist, i then said let me go to the bank rather because they were looking for a code that we dont know. I went to Absa and they tried to assist and eventually when i could now complete the transaction after trying several times the special disappeared from increfible connection website. I phoned the call centre just to be told that they cannot pick up the phone which means theres no special. I was so furious to think for hours ive been struggling and they have the audacity to tell me that nonsense. Sam the agent wanted to give me a ref nr and log my complaint. i went back to the blue route store and the manager explained to him what happened and that I was there and struggled with the online purchase. Sam took my details and promise someone will get back to me. Ive told him, I dont believe and hold and below till date no one came back to me. I phone Sam and he gave me a ref nr, with no feedback. I have screenshots of the special and all my transactions. I would like to have the phone and refuse to pay more than the advertise price. I feel.its a **** and they are trying to manipulate the public with false adverti*****ts.
