Poor customer service

Have been on contract with OnAir for 1 year 10 months, it has been 2 weeks since I have sent them an email as well as a whatsapp requesting my account statement since I don't want us to have a miss understanding when this contract should come to an end, end of August since it will be the full 24 months of this contract but till today I haven't gotten any response from them an both communication and their phones are not being answered I don't understand how are they in business if they don't communicate with their customers this is totally un acceptable. True definition of poor custumer service I am not happy at all if its not our account being debited twice then is lack of communication
