Paypal support credited twice

Hello,

I'm supporting the site for years now, and I wanted to increase my contribution. Checking my Paypal invoices I just realized that now I'm credited twice each month: once with my increased contribution, and again with the original amount. This situation reveals a few bugs:

• increasing the donation should cancel the previous subscription, but it doesn't
• the patron page links to the "contact us" page, where there is no option to choose a relevant topic to subscriptions
• just a small thing, but I love streaks, and I'm afraid that by cancelling my current subscription I would lose the streak "patron for X months". (If my memory doesn't trick me, it happened already before, even though I didn't change anything back then.)

I'd appreciate if somebody could sort this out for me, but maybe there are bugs which should be fixed for others too.

A person dealing with these issues will contact you.
Thank you for your support.

It is sorted out, thanks!
