Poor customer service and poor quality Bennet Read products

Bought a Bennet Read XTR1800 pressure washer from Makro. The pressure is weaker than a normal hosepipe. Went back to Makro on Saturday 26 Feb exactly 14 days after the purchase to find that an upgraded model with the same model number was on show for the same price that I had purchased the older model at. Complained to the in store representative that I was sold an inferior model for the same price as a new model. He was totally disinterested and said speak to customer care at headoffice. Headoffice only operates Monday to Friday so could only phone on the Monday. Was told by customer service that they can't refund me because I am now past the 14 day period, despite my initial complaint being within the 14 day period. Returned the washer to Makro the next day and the Tevo representative said they can only send it for repair. Refused to take the unit as I had left the detergent bottle behind. Made me return with the washer bottle then only took the main unit and returned the washer bottle to me!! Sent an email of complaint to Tevo on Monday 28 Feb. No one has bothered to respond. Don't waste your money on Bennet Read products. This is the second issue I have had with their products. Took 3 months to get a replacement suction pipe for a Bennet Read vacuum cleaner which was under warranty. Customer care is a joke
