Forcing sale on you

1st when your representatives called me they said that I would receive a WIFI router, when the item was deliver I opened the package and notice they have send me a tablet on 21 June 2018. I then called them immediately and said that I received the wrong package, they said no they would collect the tablet, and the upgrade would be cancelled the following reference number was received 1- ********** ********** . The I received a sms on 25 June 2018 indicating that ref number 1- ********** ********** has been closed. I was under the impression that the upgrade has been cancelled and I was just waiting for your representatives to come and collect the table. I then called on 09 July 2018 at 12:50 ********** and asked them when will they be collecting the tabled. They said that the courier has cancelled the collection, I asked why because I still have the tabled, shocked the lady said she will log another collection. I received the following reference number 1- ********** ********** . On 11 July I received Vodacom's invoice indicating that I should pay for an upgrade and installment. I then called vodacom accounts, the transferred me to numerous extensions, where I was cut off often, eventual vodacom sales extension said they are unable to help me I should call ********** . which I did at 12:50, the lady assured me I should not worry as my cancellation has been logged , she would send the courier to collect the tablet. I asked for a reference number she said I can use the same reference number 1- ********** ********** , and it should take 3 working days on 17 July 2018 at 14:38 I called vodacoms representatives again and, said that the courier still has not come and collected the table, the lady then told me the couriers has cancelled the collection. I then asked why an she could not provide a valid reason. She said she would once again request the couriers to collect, I asked for a reference number and was provided with ********** 745.. The issue is with Buy Modo and RAM couriers, please resend me the invoice indicating that the additional fees has been removed. I did my part on the cancellations and repeatedly having to call them to come and collect. I think they want to FORCE me the keep this new upgrade and table, I will not stand for this. VODACOM I hope you can resolve this matter with your representatives, and in the future I DONT WANT ANY REPRESENTATIVES CALLING ME ON VODACOM'S BEHALFE
