RAIN'S INTERNET IS LIKE PLAYING WITH THE ROUTER TILL IT IS EXCITED ENOUGH TO WORK- THE ONLY JERKOFF HERE IS ME

I have had RAIN internet since last year, THE FIRST 3 MONTHS, I had ZERO issues. It didn't matter if the signal (optimization) was 65% or LOWER I ALWAYS had internet, I could stream up to 4 DEVICES with 1080p quality, ZERO issues. Then We were all GIFTED an upgrade to 50mbps speeds, which I though was amazing, If I was getting such good service with it on the previous connection speeds this is just going to make everything even better - I thought it was CHRISTMAS! To my disbelief I HAVE HAD NOTHING BUT ISSUES FROM THIS POINT FORWARD. Every day I continue to get POOR connection, MY ROUTER CAN HAVE 95% SIGNAL - But I cannot load anything. PLEASE EXPLAIN THIS TO ME, EVERYTIME I OPEN MY EYES I WAKE UP TO SIT AND PLAY WITH THE ROUTER, REMOVE THE SIM CARD, SWITCH OFF FOR 10-15mins, RESTART 100 times!!!!! I AM NOT JOKING! All I get are emails for RAIN explaining to me the above steps - yet I continue to struggle EACH DAY This is NOT WORTH PAYING R699.00 per month! This is literally a **** at this point - I WANT RESOLUTIONS I WANT A SENIOR ADVISOR/MANAGER/ COMPETENT PERSON TO PHONE ME! IMMEDIATELY - NOT TOMORROW - NOT NEXT WEEK, TODAY!
