Tablet under warranty not fixed but returned ruined

My pensioner mother Setsolo Joyce Ntsoane bought a Huawei Tablet T3 worth R3399 (IMEI: ***) on 7 August 2020. At the end of March this year she realised that the charging port is broken and she sent it to Exact Protea Glen Mall as the phone is still under warranty and the store said they will take it to Huawei for repairs.

They kept the phone at the store for 3 weeks with no action. The store then decided to send the Tablet to Vodafone Jabulani Mall for repairs. My mom got a call informing her that the tablet is going to be picked up from Exact Protea Glen Mall on 18 April 2022 and was quoted +/-R1500 for the repairs. My mom agreed. On the 24th of April 2022 my mom's grandson went to Vodacom Jabulani Mall to check on progress of repairs only to find that the phone was still at Exact Protea Glen Mall. He had to go fetch it himself and manually take it to Vodacom Jabulani Mall. On the 15th of May he went to check the progress at Vodacom Jabulani Mall and paid the R1212.70 charged for the repairs and collected the tablet.

Only to find that the charging port has been repaired BUT the Tablet came back without the dialer app (she cant access contacts/make or receive phone calls). The phone was returned to Vodacom Jabulani Mall on the 20th of May by mom to report this. They tried fixing the dialer issue in the store and couldn't and advised her to leave the tablet behind. After a week they called and said the Tablet was ready for collection. My mom was only able to go on 2 June 2022 only to be told that they couldn't fix the dialer issue that they caused, so they decided to remove the replacement charging port and refund her the R1212.70.

So now my mom is now left with a Tablet which is in a worse condition than it was when it was taken in for repairs. The tablet now has a broken charging port AND a missing dialer app. Exact Store Protea Glen firstly had no sense of urgency when handling this. It took weeks of NO action and my nephew ended up having to pick up the Tablet himself and take it to the technicians who then ruined the phone. Exact Protea Glen failed my mom and caused her so much distress. She has been unable to communicate with lots of people she depends on and it is now nearing 3 months with a broken tablet. Yet the tablet is still under warranty.
