Comp Bronze 5 never ends

No matter how many wins I get, consecutive or not, No matter how many times I top 15-18k healing in a match, no matter how good my team and I do, After every 7 wins im still at B5. What the hell is happening. I thought they said this was fixed. Ive racked up at least 35 wins in comp now and havent jumped rank once. Meanwhile friends of mine are going straight from bronze to gold in first 7 after placements. Please halp.
