Staff attitude stinks!!!!

I had a contract with Intellicell which ended today, 31/10/2019. Despite not wanting to upgrade or renew the contract, I receive numerous sms a day asking me to upgrade. I phoned the customer service to confirm that I have no intention of continuing the contract and could they please remove my alternative cell number from their data base. While still speaking with the consultant, the phone was put down in my ear. So glad I am done with this company.
