Shocking after sales service!!!

I have been a client of vodafone for more than 10 years now and never had a problem with them, until now.

I have been trying to cancel some of my contract numbers now for 3 months. It was due for cancellation end of April 2020 so I phoned around the 20th of March to cancel it and they said they did it and my last bill would be end of April.

In May I received another bill from them for the same numbers that I cancelled. I was shocked so I phoned again in the middle of May to find out and to cancel them again. The person apologized and assured me it would be cancelled and that the last bill would be end of May which I accepted.

Now in June when I followed up on this it turns out it was not cancelled. Now I am phoning for the third time to do this!! Really what is happening there? Does nobody know how to do their job? Every time I phone it is a 10 to 20 minute process to get it done.

It really is a shame. Think I will just take all of my business else where from now on
