Lies, Lies and more lies from Mondo staffs

i took out a contract with Jessica Zikhali from Mondo and i clearly explain to her that i wanted a blue handset and to use my prepaid number as the contract number. She did not tell me that they cannot port my number but i will have to go to a Telkom store to have it done. Mbali her "supervisor" who verified my details, i also told her about the colour of the phone and the porting of my number. she also did not tell me anything about going to a Telkom store. A delivery was made on the 11/06/2019 and i phone the Mondo offices twice on the 13/06/2019, spoke to Oscar who also gave me incorrect information since the new sim card had a new number that was activated. The second time i spoke to Noxolo who also could not help but she said she has sent an email to Telkom and someone will call me before the end of the day, no one phoned. I phoned on the 14/06/2019 and spoke Taren who assured that before the end of the day my problem will be sorted but that was a big fat lie. i phoned again on the 18/06/2019 and spoke to Taren again luckily and he said i should wait until the 20/06/2019 for my number to be ported and activated to Telkom contract. i asked for my contract to be cancelled as it was still under the 7 days cool off period and because i have used so much money calling them and getting empty promises and more lies from all the staff members that i spoke to Taren said he has done the cancellation and the courier guys will come and do collection of the handset. I called on the 19/06/2019 and spoke to Trushka because i wanted to confirm when will the courier company will be coming, She confirmed with Taren and told me not to worry since all the arrangements were done for the collection to be made. i called again on the 24/06/2019 and spoke to Ndumiso who told me that the collection request was not done and when i asked if was the cancellation done. He said it will only be done once they have received the handset. he promised me that Taren will call me at 15:30, as usual that was another fat lie. the handset is still with me and this will cause them to end up billing me for something that i did not ask for and did not use. By them delaying the process of collecting their phone is causing issues for me since now i have to look after it for so long. I have never been told anything that is a fact from the Mondo staff in fact i ended up using my money to call them daily. Since they say calls are recorded they should go back and listen to all the conversations.
