Good morning I had contacted Hillcrest Classified Information to sell a old stove & the person rep**** that they will come to me & buy it. Everytime I messaged back they make excuses for not coming but confirmed again they coming.Last Saturday I was messaged they will be at my house by the morning. I cancelled my appointment & waited & nobody came till date. This is very frustrating as I kept asking the person are you still interested in the stove & the answer was yes. This type of business is very unprofessional. Thank you Prabern Padayachee
