Took my money - No service - WORST SERVICE

Waiting for 4 months to get my dishwasher repaired after having paid for monthly subscriptions and for the part of my hisence dishwasher. The call centre, which is the only way to get through to anyone, cannot help! Couldn't get through to a supervisor or manager, left messages and nothing. Until i posted on social media, then Candice the manager called me, only to give me false promises just like the call centre agents. I guess it's the nature of their company. Call centre knows my number and by their own admittance can identify the caller, so when i call they put me through to an answering service, No one is willing to take responsibility. They refuse to give me a refund, when i say refund they hear; where's my part! Listen to the customer! REFUND ME! This company is run like a bucket shop. Needless to say the absolute worst and frustrating experience!
