Cellphone repair

Good day,on the 26th of June 2020 I bought a Mobicel Beam for my 10 year old son at Ackermans Promenade,the sale was put through at 17:00...only the following Friday evening he told me the phone was freezing,we took it to the shop the Saturday morning and was told the 7 days has passed which meant they have to send the phone away for repairs,and the phone will be collected from the store within 3 - 5 days...and it will take up to 14 days all in all for the phone to be fixed...last Wednesday 22 July I called the store and was told they dont have any info as to when the phone will be fixed as it has not been done yet...Friday 24 July I was told the phone was only collected the previous day!!! and that it "will" be fixed within 3- 5 working days..Vodacom is the service provider...I feel this service is absolutely disgusting!!!! to say the least...everyday my son ask me when is his phone going to be fixed and I cant answer him...
