No delivery-****** devices-continued billing-no response to cancellation

Good day-I was contacted by CCISA to upgrade a 3G ****le with a router and data, didnt realise was a subcontracted company, wsnt told... Never took delivery, i hve called no less than 6 times, called at four stores, countless emails to various addresses. NEVER, have had a call nor email back regarding goods never received from courier, i gather this has been ****** by either the CCISA, Courier company or MTN staff. WHOS PAYING? I am. I stopped my debit order this month being Jan 18 in hope of getting a call. Nothing, cut my service, called in at MTN Oakfields. They have contacted the accounts people who cancelled my services, 2 weeks now, nothing. Im getting calls , twice now from Dollys wanting to upgrade my cell account, ARE YOU DELUDED!! I dont wish to use MTN ever again. Is it difficult to understand. Please will some bright spark call me, give me some customer service. The worst thing was call centers and computerized services. No client contact, stop service, no discussion
