Held hostage by Micros

I am saddened by the treatment or lack thereof from Micros. My rep/account manager is Lance and after a fire that broke out in the place of business, I requested to cancel services as from since, I have not been making use of the machinery (but am being duly billed) Lance advised that I signed a 3year contract and when I requested the digital copy, we were both in agreement that the contract would end in September 2021. When September rolled around, I again asked for the cancellation, only to be advised - by the very same Lance that I was never in a 3year contract instead a 5year contract and should I wish to cancel I would be liable to a payment of R90k plus... Mind you, the main reason for cancellation was affordability as I was releasing the business from my care. After the new info of a 5year contract, I then requested details of management as I no longer wished to communicate with an account manager who has NEVER been present. To date he has never forwarded this information, and I have now contacted Micros directly, logged a ref which has not been responded to. I was today given a Dons' landline number which doesn't exist... The biggest issue is that I continue to be debited (since January 2021) though I have not had the systems activated.. So basically Ive been held hostage by Micros, paying R8k monthly from Jan 2021 even though the machinery is NOT in use. Over and above the fact that Ive paid R80k for NOTHING, I now need to pay a further R90k plus for cancellation whereas I was advised that our contract would come to an end in September 2021
