Incompetence at its best

Iv been struggling now for more than 2weeks to cancel my data sim contract with vodacom. I emailed them all the necessary documents and paid the huge amount they requested from me to cancel early. They sent me a ref number via email as speaking to the consultants are just as useless...... Today I received a email saying the matter has been resolved but now they canceled my Fibre contract instead of my data sim contract. How *********** can you be? I'll never do business with vodacom again. I need the Fibre for work.... They so *********** and useless.....
