Poor system performance

I signed up with Wetility for 36 month solar contract of 1500 as my electrify usage was 3000 per month. I was told with their service I will be able to save up 60% of my electricity cost hence I believed that I can afford their solar system. The 60% reduction we experienced for 4 months there after it reduced to 30% maximum

I requested for their technician to investigate, it took them almost 6 months investigation to ultimately tell me that the sales team sold me an incorrect package hence I only experience 30% saving at the same time buying prepaid weekly electricity of 600. They told me that I can change the contract to get more solar panels and batteries that will decrease my prepaid electricity cost - which was clear more costly and impossible to do During that 6 months investigation the smart gersey device was removed as they were tracking or monitoring my house hold electricity usage. I realised in November that since April when they removed smart gersey they did not stop charging me for it. I call bongiwe at utility and asked her, why and she explained that she forgot that the contract needed to be amended in order for the deduction to stop. It's 14th December bongiwe nolonger answers my calls, emails nor what's

Worse part of all this saga, being sold a service that ultimately caused my electricity bill to increase by 50% instead of reduction.

Am beyond frustrated with Wetility
