Rain internet provider

I’m paying for poor services, then I went to the store with that loop device, they then did something and my address was changed to Kempton park and I’m in Boksburg, so all my 10gb monthly out of zone was used up and I’m left without internet connection… this is not my first time experiencing this poor service from rain. They always making promises they don’t keep… I saw how people take devices back because they don’t work.. and the fact that the store has no contacts number for someone to help you, and the call centres are not helpful at all.. when they just started years ago, they were the best, and as the years go on they grew but service became ****
