Pathetic service

Never ever have i come across a company so *********** before. This has been going from bad to worse! First Ive been overcharged then i get told the billing will take upto TWO months to be resolved, then I am unable to purchase a data bundle cos the sim apparently isnt active! Been promised call backs to date nothing! If the call centre people arent ******** they just plain rude i think ive bot had it with Telkom
