Please could you indicate how long we are expected to wait for contact (let alone resolution!) by e-mail. I am still awaiting contact on an issue first raised on 7th June.

Here is a summary

070618 Issue raised
090618 Further Information requested via PM
??0618 Information provided via PM as requested
150618 Update on status requested
170618 Agent Andrew replied that case still being investigated. but results would be posted in this thread when complete.
180618 Agent Pavel said ticket submitted and would close topic and contact me via e-mail.
260618 Still no contact or update

I would therefore suggest that topics are left open until resolved so that you are able to seer which ones you have still to deal with

I'd also suggest that you indicate timeframes for resolving these issues rather than leave us to continuously check for updates from you.
