This is to draw your attention to the unsatisfactory support service by your company. I handed over you all the details what you
asked and your team assured to resolve the issue as soon as possible but failed to fulfill the promise.
Time is essential and our client is getting late. Please fix the issue without undue delay.
I hope you will take a serious notice of this complaint immediately, Should you fail to do so, I will be requesting a full refund of all monies paid.
