Non existent service and now they do not pay my money back

Incredibly disappointed with the non-existent service from Liptronics. I have had multiple issues with two Samsung Washer Dryers. Whilst under warranty, I can say that they did attend to the issues, although at an incredibly slow pace. Once out of warranty, I contacted them for support. Logged the required callout firstly with Samsung, then directly with Liptronics stating the reference numbers received. After weeks, I called and they "found" the logged call and said that I have to pay an upfront fee for the repair and callout which I did the very next day and sent the POP to Chantal M. No one ever pitched on the required dates, and after further waiting I eventually went to their physical offices. I asked to speak to a manager, but they did not want to call any person to speak to me in their own premises. They (the two ladies at reception) then said they will refund me the amounts paid R776.24 for failure to come out to my house, and that they will provide the POP once done. I have followed up on three occasions (27 March, March 30th and April 15th) - no one even bothers to respond. Incredibly disappointed. I could not recommend using them until they rectify this whole situation.
