Cancellation still not done 3 days later!

I've called the eftpos call centre, routed to customer service dept. on 08 Jan 2018, spoke to Thobile(very friendly and polite call agent), advised that I'm cancelling this card machine with immediate effect due to the exorbitantly high monthly bank charges/fees/rental costs. Ref number ********** 7. No one has contacted me since, poor customer service/after sales support is another reason why I no longer wish to do business with eftpos. Now please arrange for someone to collect your machine urgently and cancel this arrangement between us as I've decided to go with iKhokha to service my customer's card paying needs, your full and detailed monthly charges was not explained properly upon signing this contract. I was only aware of the R249 rental charge and transaction fee per swipe, not everything amounting to R1000 a month.
