simcard never worked since delivered in September

EXTREMELY UPSE M since i received my sim cin from RAIN in September i still cannot use it,, besides the fat that they've been deducting money from my bank account, its been back and forth emails, last week they realised its the simcard that they sent me that was faulty they ordered a new simcard which was delivered yesterday, until now the so called replacement simswap card is still not working i tried to call RAIN, and a very rude consultant who hung up on me, is very *********** its like she's guessing what the issue is and what needs to be done, i demand a refund AND DEMAND AN APOLOGY, REFUND, AND THEIR SENIOR MANAGEMENT TO CALL ME BEFORE END OF BUSINESS TODAY.
