Horrible Restaurant Partner Service

I am a UberEats restaurant partner, and as of late I am getting horrible service from them. I have been double charged for the month of March for my subscription fee, taking 3 weeks for a response as to what and why there is a double charge, to be told there will be refund on my account. Nothing of the sort happened. Now for a second time, I have had payment held back for two weeks due to another double payment being added onto my account, after paying a double fee the previous month. No response on email, with a useless call centre.
