Mondo telkom data contract

I took a mondo telkom data contract around june/ july this year..bad news from day one..2 routers were send to me 2 routers implying I have taken 2 contracts , I immediately brought this fact to their attention, askingthem to terminate one router , they told me thatthey have to terminateboth contracts...and that i have to start from scratch...they send the courier to retrieve those routers...since then I have been bombardedwith phone calls and emails to pay, they call, I keep explaining, it is apparent no one is listening..they debit my bank account..I reverse the debit....I wrote their collection department an e-mail...it is apparent this matter will not be resolved unless a 3rdparty is involved to relaythe message in simpler terms...People should stay away from Mondo..period
