Non-acknowledgement and no refund!!

I have been using Mtn for as long as I can recall without any complaints, but this year March 2025, they managed to lose my trust in them. After being called by one of their agents to 'upgrade' my home internet package, I was deceived. A new line was registered without checking if I have coverage for my area. I then called in to cancel the contract the very next day to cancel the contract. I was told to take the router and Sim card in store for a cancellation. In store I was told I had to call in to request a cancellation. I insisted that we call into the contact center to verify exactly what to do. They then 'put me through' to the Retentions depth which was already closed for the day. After calling in everyday thereafter to cancel, and after either being cut off, transfered from pillar to post, or them having a bad connection, I wrote an email to the complaints dept - who never got back to me. I then called in one last time and a lady managed to put in a request for my cancellation and now refund - since I had been debited for a service I never used. 48 hours later no none has gotten back to me, not even an email that my requests had been received. MTN you have dropped your standards in the caliber of agents you now hire, who lack customer care and common decency, who cannot even perform a simple job function. No one seems to have adequate and basic product knowledge or protocol about simple requests. This is not the last time you will be hearing from me as I am taking this matter further. A cancellation request and refund cannot take 2 months to action and resolve.
