For the past two day...

For the past two days I've been trying to get in contact with Rentoza but with no success, I have an 18 month subscription on a laptop with them but the subscription term has gone over the period and they are still taking money from my account, 21 months already... My question is why does Rentoza not communicate with their damn clients but when a payment is overdue they are quick to communicate with us. This is really the most unprofessional experience I've ever dealt with. Poor poor management and customer service.
