USELESS COMPANY

I paid my account and asked Nesma to change my debit order details, nothing was done about this and i even sent proof of payment to Nesma of the payment, now Tracker has handed me over to the lawyers who keeps on phoning me, i have even sent them the proof of payment and email that i requested Nesma to change my debit order details, and even the lawyers are as useless as Tracker. I have left numerous messages to tracker account department to phone me back and NOTHING, this is from 22 October 2015, if they are so USELESS with this how can anyone trust them with their assets!!!
