What's wrong with competitive? (Overwatch)

Idk if I putted everything right but anyways. I have a huge problem with competitive games rn in Overwatch. VERY OFTEN I can’t join them after the tittle “joining match” or something like that. It just loads until I get kicked out of the queue. Then it counts like I left the game at the start and takes away my sr with having a suspended time. I can take it one time but I had that that for a 3 times and I lost 100+ sr because of it. I’m very dissapointed, because I achieved my rank really hard and get tired of it.
Can someone explain what am I supposed to do in that situation? I really wanna play competitive but afraid to have it again
