I have bounced around many hosting companies, to find they aren't very good.
I currently have reseller hosting with certa, and its the best package and service i've received from any company! I have been with them a year , and still have no concerns or complaints.
Tickets are answered fast, even throughout the night. My sites or servers have never been down and they are not stringent on resources when it comes to hosting.
A*** Highly Recommend,
Absolute value for money
