MTN pathetic service

Mmalepo *** to whom it may concern MTN Management team,

I received a phone on the 24 April 2019 which was sold by Mobiles Plus on behalf of MTN. on the 26 April 2019 I opened the box found the phone but no sim card. when I called them back their argument is that I have signed the tax invoice which indicated that the sim card was delivered as well. the consultant from mobiles plus said to me when I get the phone I must not open it just for in case I return the device. I have been calling Mobiles Plus, MTN and courier company from the 26 Aprill 2019 to yesterday 12 July 2019, no one wants to take responsibility. I don't even know my cell number and I have been billed end May and June 2019 for the device that I am not using cos I don't have the sim card. when I go to MTN shops, I was asked to pay R115 for the sim card not sim swap. Sim swap is another charge. I have been put from pillar to post with no help. Between the 26 Aprill 2019 to 12 July 2019, I spoke to the following people on ***,*** and ***:Matthew Chellan(Mobiles Plus), Lakeisha Michaels(Mobiles Plus),Vanessa,Zanele,Faith,Zamokuhle,Gregory,Zama,Pretty,Chrostofel,Samuel, Nivashnee x2,Nokhanya,Neliswa,Mamotse,Sibusisiwe Mbebe, Denishia, Mbali,Mokeni?,yesterday Trinishia and Desmond. still no help.i also called the courier company spoke to Joseph.

yes I signed the tax invoice and didn't open the box cos I was told by the consultant not to open the box for in case I was going to return the device. I thought the sim card was inside the box. For two months I have been billed for the phone that I am not using yet. This is a pathetic service. I would like to cancel this contract. I cannot go on like this.
