Bad and ********* service from telkom

good day I app**** for an LTE wireless smart-broadband from telkom maponya mall and i was told that i should pay R700 for a deposit which i did. then on the 19th of November 2017 i went back to the store and i was given my router as well as the sim and i was told it will be activated in the next 2 hours. the sim card was not activated the whole day and decided to go to the store the next day, the staff over there still was unable to help me as she said she logged a call and waiting for feedback and i should wait another hour or 2 to be activated then i went home but to no avail the sim is not activated which i decided to go back again was unable to help me. i requested that she gives me my contract as i did not obtain it and she said she cannot print it as my sim card is not activated. so i decided to call telkom helpdesk to clarify the issue and the consultant said it should take at least 2 to 72 hours on their side to activate and suggested i go back to the store as they are the ones who can activate the sim instantly. so nobody is assisting me here and you guys expect me to pay 750 every month for something which is not even working its been four days already and i need clarification on this or to refund my deposit and cancel the contract so i could move to a better ISP
