Disgrace service

I bought 10gb of data per month which comes with wifi router online from telkom mobile in June 2019. The device was delivered on the 18th of June, to my surprise it was not working and i called telkom immediately. They said i should wait for 24hours and nothing happen. When i call again, i was told to wait for 72hours. I called again and told to wait for 5 days. I took the device to the nearest store for help but none. I then call to cancel the contract which took them donkey years to cancel, instead i was send pillar to post until they bill my account. I then went to the store again for cancelation which they managed by sending an email. Telkom still bill my account even though i have never used their services. Their explanation is they will only stop deducting when they have collected their device. It's now almost end of November and i call them daily but failled to collect their device. Everytime they say they will escalate the message for collection but that never helped. I've spoke to countless managers like Wonke who promised to call back till to date nothing. I'm so disappointed in telkom mobile staff due to their unprofessionalism. It's with a great regret to have made business with telkom.
