Teljoy has terrible customer service

I have app**** for a fridge. Got the wrong one delivered to me, signed papers after delivery guy told me to keep the wrong fridge and phone my sales person to arrange for a new one. After speaking to the sales person she informed me that they need to investigate. Got a call back from the sales person where she told me the delivery driver said Im lying, she told me she is going to speak to the manager and she will 0hone back in 30 mins. I never received that call. I phone numerous of times left alot of messages and then I got a hold of her. After telling her I would like to cancel everything she did a new application for the right fridge. Received messages that i need to submit documents after they have everything. Phoned teljoy once again to follow up on application and to find out why i should submit documents. Without any luck as everytime i phone the sales person is not available leaving urgent messages with no respons, sending emails without a response.
