Cancellation of contract because of relocation

I have an account with skyworks Telecoms a 36 month contract, I'm moving from mpumalanga to Limpopo on work related, I informed skyworks to terminate my contract and they refused to terminate and say I must pay until 36 month, and there is no skyworks network in Limpopo, I cannot pay for something that it will not work in Limpopo, their contact details are *** the name of the lady there is Lee, she is very rude, she is in cancellation department. Skyworks is not user friendly, do not even try it.
