Extremely bad customer service from Telkom

I purchased a Samsung Galaxy A53 contract on Tuesday 13th December 2022 at Telkom Lansdowne Corner . On Saturday 17th December 2022 I experienced a problem with the phone, it kept detecting moisture in my charging port when there was non and I wasn't able to to charge the phone because of the safety feature. I went to the Telkom Landsdowne Corner on Monday the 19th December 2022 and was told no one was able to help me because the manager wasn't in but she would be later that day and they would contact me when she got back. They neglected to contact me on that day as well as the day after which was the Tuesday. I was in store within my 7 day cool off period with a faulty phone and all the staff neglected to assist me and refused to do an immediate swap out and I am still sitting without a phone because they insisted it needed to go for repairs and neglected to take my complaint and urgency serious.
