Poor service

I would just like to express my dissatisfaction with the absolutely poor service that I have been receiving from Vodacom following the purchase of my new Fibre line - specifically referring to the Wifi Extender that I have been continuously following up for installation. I have already paid for the device but has not received anything yet. Been following up since end of March 2018 for the 4th time now via telephone and Facebook to now ends. Utter frustration and pathetic service! My service reference number is SR180 ********** 10. I am just continuously ignored! In what world does a company take money for a item before they deliver the item! My account no. is NM046671-0 and my Solution ID/PO no. 1- ********** 3131/1. I expect some services please!
