HomeChoice Pathetic services!!!

I have been a customer of Home Choice for approximately 10 years. On 18th of May I ordered a HD and Heater. All of a sudden HC wanted me to sign a debit order which i refused because I have never missed of skipped a payment. I have canceled the order twice. After the lady phone me on the 26th of May 2020 and I said to her that I already canceled my order a week before when HC phoned me regarding my order, my order was dispatched the next day(27 May) without my consent. When fast & furious couriers showed up on my door step, I send both the HD and Heater back with them. Now since the beginning of June I have been trying to sort out my account. HC has credited the HD but the Heater is still on my account. I phoned numerous times, requested to speak to a manager, send emails, send FB messengers. Every time they promise that a manager or customer services will phone me back. Its been 3 weeks and I am still waiting for someone to phone me so i can sort out my account, because i want to settle it and close it!. I WILL NOT RECOMMEND HC to anyone, because they are quick to phone if you want to order but absolutely pathetic in their customer services, when you are trying to sort out your account. This order should have never been dispatched in the first place as i have canceled it twice before they decided to send it to me . Now i am struggling to sort out their mistake so i can close my account. I am so mad at this pathetic excuse of a business, its not even funny.
