Monsoon - worst customer service and knowledge of their own product

We engaged Monsoon to install an Inline water solution. The sales person provided the solution and we opted for the in-tank pump. It was confirmed the tank was available, then just after that once we had followed up for the umpteenth time, the pump was not available. So we agreed to go ahead with the external pump. Again, we had to chase them for an installation date. Just complete lack of service. The sale was made, but there was no follow through or customer service. System was installed (the workmen were brilliant FYI). We requested an electrician to do the final cabling, the sales person promised it would happen on the Friday...and nope, but the Sales guy had to leave and clock out because he had to move a couch and it was clearly more important than ensuring we had a working system. On closer inspection the next week and getting to grips with the installation, we noted that the "inline" valve was not installed. So again, we go through the calling and waiting process. Extra valve is installed. Over the weekend, the pump keeps dropping to 1,2kpa and cycling like that for 30 min (not good). We reset.... seems fine and then starts again. Call Monsoon back to check it out - they don't know. Repeat of issue, call them back - manager comes out, oh yes not right, takes unit away to have checked. Nothing wrong with unit, they return it and problem starts again... did we hear from them to check if it was ok - NO!! Hubby does some googling, figures out problem, adjusts KPA and solved. Oh and the price quoted versus charged was R7k more expensive - dont even get me started on that issue. POOR POOR service, so damaging to the brand as we will DEFINITELY not recommend Monsoon. And that Sales guy needs to learn CUSTOMER SERVICE before he destroys your Brand!
