Poor Service

A few weeks ago I laid a complaint about your company's unprofessional work ethic. They left my parcel at the neighbours without my consent and a person with the name of Tanya Deonarain responded saying that the matter is being looked into and that I will be contacted shortly. I contacted Tania on 9 July 2015 with regards of feedback as the initial incident occurred on 3 July 2015 and she is also not getting back to me. Weeks have passed and till this day I have not received an apology from your company or a guarantee that this will never again happen. Not a phone call, not an email, nothing. It's unacceptable!
