Telkom - Poor Service

I got a Telkom contract through Mondo Mobile. Two HI-Sense phones at a rate of R199 per month. One of the phones was broken and Mondo had to send it Telkom to get replaced by another phone. It took more than a month for me to receive the replaced phone. They have been deducting a debit order for the 3 phones instead of two. Ive been trying to get hold of Telkom, you hold on for literally hours for a consultant to pick up the phone at Telkom. I've used their website to send a complaint to their complains department, and till date I have not received a call or any response whatsoever. I cannot keep on paying for 3 phones, if I only have two.
