MAKRO EXTENDED WARRANTY NOT GOOD SERVICE

I bought an HP 4675 DESKJET printer on 25 Jan 2018 with an extended warranty. On 15 Feb 2019 I took the printer to Makro Centurion and was informed that I must complete a extended warranty form which I did. I was to keep my printer as HP will contact me to do the repairs on site. To date nobody has contacted me and I cannot contact Makro on their number provided ********** as nobody answers the phones.
