Unhappy with dstv wish there was other service provider I can use

Hi I have been a loyal client for over 10 years paying my account in advance but for what??????

I had to buy a new decoder about 5 months ago as the old one was no longer compatible which was no problem I got technicians to assist with the setting up of new decoder and all was working wonderful but for one week then the explora started giving error we had it on insurance and they changed it once again we got technician to help and it was working for 3 days ever since it's been giving errors when we manage to fix the one the other one goes of we phoned the call center with no luck we were just told to get technician out once again this is not a technician fault but dstv fault as they don't know how to assist us and we are paying for a service we don't get or can't use every time a technician get called out it's 400 above our fees we get charged
