Intec still refusing to pay our refund!

I registered with Intec in Oct 2014. Due to lack of service and breach of contract and agreements, I cancelled my contract with them in Jan 2015. After all the docs and certified copies of everything they demanded, the cancellation was only acknowledged at the end of Feb 2015. The cancellation was accepted on the 23rd of Feb 2015 but they dragged it out and it was only \officially"registered on the 10th Apr 2015. After 90 days from the 10th of April"
