Very difficult. Only chat app is available for customer, else you can call customer support and waste your energy, time & money.
They don't let you connect to the customer service at all. They only provide robot customer service and the robots do not provide proper answer. Plus, if we raise a query, we neither get to see the status of it nor we get any response from them..
They don't respond. If at all they do, they don't listen to your complaints fairly
