Bad and ********* service from CellC outlet

I am writing this in frustration due to the manner in which Cell C is handling my issue, and in the process undermining my child's education. My son, who is an online learner, utilizes a laptop purchased from Cell C, which recently developed a fault with its charging port. Upon realizing that the device was still under contract (but out of warranty), we took it to a Cell C outlet for repair which we were willing to pay for. We were instructed to leave it at any cellC branch, which we promptly did. The device had no issues apart from the faulty charging port. If there had been any additional problems, the individual who logged the device for repair would have noted them, and we would have acknowledged it. However, upon its return from repairs, we discovered that the screen was cracked and there was a dent, both of which were not present when we submitted it. Naturally, we refused to accept the device in this damaged condition. We immediately brought this to the attention of the staff at the Cell C outlet, who assured us they would send it back for further repairs. However, we are now facing demands for payment for the new damage, with Cell C claiming that we brought it in already damaged. This assertion is entirely false, and we fear that this dispute will only prolong the resolution process, causing further disruption to my child's education. I have been communicating with Cell C's customer service team via email. I kindly request that the customer service personnel at the main office of Cell C follow up on my email with the subject line: "Attention Nelly: Urgent Request for Resolution Regarding Laptop Repair - Job number: GPJOH473532." The laptop was delivered to the Cresta Mall Cell C outlet and was received by a male consultant there. Following that, I have been in contact with Nelly.
