Unhappy Customer - No After Sales Service

Been struggling with connection and data speed for the past 2 months, I contacted the call center and the online chat thing but the after sales service is pathetic. Network running on Edge speeds and the worst is they are using 3rd party companies as service providers who can actually come to your area to assist with coverage issues or can go the extra mile to ensure after sales service. The call center tends to always push the blame to the devices used but never go into detail on the problem and do a proper analysis on the error with coverage or heat maps or any other issues maybe reported in the same area to actually find the root cause of the problem, but hey its easier to pass the buck. The fact that the coverage map on the website shows coverage in the area is another issue on its own and dishonest with false advertising as mentioned by many on this platform. To try capture the very lucrative almost saturated market of Wi Fi a company really needs to focus on customers and after sales service as price wars are settling in from all MNO's and WISP's in SA and if you want to gain market share you need to not just compete with them but be better and Rain you are failing, you are letting your customers down.
