Re: Compliant Letter Regarding Poor Parking Facility in the Locality

I'm writing to express my dissatisfaction with the parking situation. My name is Ojong, and I'm the CEO of ABC Boutique. My enterprise is direct across the street from your Bank. I've seen that your staff park their automobiles in front of my Boutique daily.

My employees attempted to stop them personally but to no avail. For my customers, I have a legally designated parking lot. My clients are also inconvenienced as a result of your employee's illegal parking. I suggest that you issue a warning to your workers. Also, I strongly advise you to pay attention to your parking assignment.

I respectfully beg that you resolve the situation as soon as possible. I would call the police commissioner if no response was received.

Yours Faithfully,

Re: Compliant Letter For Receiving Damaged Goods

My name is Jones, and I am from Buea, Cameroon. I ordered my children's sneakers from your website on March 10th, 2023, with order number 5287173. I choose the cash-on-delivery payment method. I received my order on March 12th, 2023, and paid the whole amount of 20,000 Frs, as stated on the bill. Furthermore, when I checked, I discovered that one of the shoes was a different shoe size than what I had ordered.

We were dissatisfied with the damaged items and would appreciate it if you could send us a replacement as soon as possible. Please keep in mind that faulty items might harm a company's reputation, and we, as customers, may never want to purchase with you again.

Please send us further information on how to replace our purchase with the right shoe size. Upon delivery of new and suitable shoe size, we will also return the old shoe in our possession. Please provide a fresh bill to correct the quantity of old and new shoes so there are no misunderstandings. Along with this message, we have attached a photo of the problematic shoe for your reference.


Yours Faithfully,
