Sectigo SSL Certificate Reviews

I have just purchased a Wildcard certificate from Comodo. I initially called them to ask a few questions and we changed some e-mails, they answered in the same day which was very prompt and thorough in detail. We went on to discuss different payment options and whether Comodo could provide a Pro Forma Invoice so my company could arrange a payment to be setup. Without hesitation Comodo arranged for this to be done without any complaints, even when amendments were needed within the initial invoice this was corrected and sent out without any hesitation. Once the payment was initiated we finally we made the request for the certificate, with the common name mydomain.com and submitted to Comodo, I forgot the most important item the wildcard character (*). The guys in Comodo got in-touch and requested a new CSR to be generated, once this was provided to them they accepted the request, again with no problem or issues. Some days later my company finally make the payment and immediately COMODO send us the wildcard certificate, but it didn't work. A message appeared saying that "private key don't match with the certificate", again no problem. I called them and the guys at Comodo suggested we generate a new CSR with a new private key, which I subsequently did and submitted, after 5 minutes of submitting the new CSR I received the new certificate, everything OK, working properly. My account manager was Nilesh Patel, nice guy, very prompt and efficient service. Overall a nice company to work with, I was treated with a personal touch which I a rarity these days.
