Great service from Denise

I sent an email on the 09th of June and again on the 21st of June 2021 and still had not received a reply as I needed to be credited for 14 days downtime for May 2021. I called the billing extension yesterday and spoke to Denise who assisted me and was very polite, friendly and listened to why I needed to be credited as she said she will send the invoice to the relevant department to be updated. I received my updated invoice last evening and I was only credited for 10 days. I called this morning and spoke to her again and in a short while an updated invoice was sent to me with correct credit app****. So thank you Denise for the prompt and effecient service.
