EI Changed (Canada) PLEASE HELP!!!!

I’m in Canada, specifically Ontario. I’ve been on sick leave for about 6 weeks because of corona my dr wrote me off with a note due to medical reasonings as well, not just virus related. So I applied for sick leave, the lady directly from EI called me & helped me (I did a call back from service Canada, & they put in for an urgent call back from EI), she put me on the 15w sick leave we are entitled too, it would take me right until my due date almost the my mat leave would start.

I was eventually approved & have been receiving it. This morning I wake up to an email stating to check my correspondence page for changes. They just changed me to regular benefits. Saying I am entitled to 6 weeks, but have 6 weeks paid. & nothing else... it makes no sense.

They’re putting me on regular EI & not transferring it over to my mat leave? Has anyone had this happen to them? I’m so confused & I’m going to be pissed if they tell me I have to go back to work when I physically can’t, & even if I wanted too my work isn’t even open. Also I’m not sure why my maternity leave isn’t being rolled over? The only thing I can think of is now I’m 32 weeks, which technically makes me eligible for mat leave now, do you think they’re just going to tell me to us that instead of sickness? That’s not fair. I’ve put in for a callback but I’m really upset/scared because it makes no sense why it’d be changed

Edit: I called EI. Spent over 1.5h on the phone, my call was being connected to an agent, they picked up & HUNG UP!!! I had placed a call back from service Canada received that this afternoon their advice.. call EI. So I demanded they put in a call back. He did, but he said I was lucky to even receive one the first time. I said if I don’t then I’ll keep requesting them & trying to get through. Basically they said there’s no valid reason why it was switched so I have to speak directly to EI. This virus has just created such a back log & now they can’t keep up so it’s screwing up a lot of thing for a lot of people 😒
