Telkom jabulani branch

Telkom jabulani branch worst service I've ever had after having 3 contracts with them and my phone samsung note 20 having a screen problem and taking it back and them telling me they won't take the phone after seven days can my contracts end and the sad part it has only been 3 months since I've upgraded so 3months vs 24months with a broken screen so can it end with them would never advise anyone to open a contract account with telkom hell no
