No Feedback / Passing the Buck

I submitted a phone for repairs with Vodacom Repairs Menlyn and when I received the phone back the charge port cover on the phone was missing, because I still had to book it for another repair I was promised to get it back with the next repair, which I submitted on the 070215, it was ready for collection on 100225 but l yet again the charging port cover which was promised to be returned was still missing, I was forced to take the phone to which I refused, I told the consultant helping me that I will collect the phone once I have the cover which was taken, she then said she'll call me to collect the phone, it is almost a month and everytime I follow up with them I am told the technician who was busy with my phone is not at work. I fail to understand why the matter is taking so long and with no one giving me feedback, I am the one to always follow up and this technician is always not there when I follow up, is he the only technician who works for Vodacom, I am disappointed that I am such a loyal customer to Vodacom, never missed payment, I have more than one contract with them, but I am of no importance as a customer. Extremely disappointed
