Unprofessional they dont know what they are doing

If I could I would give 0 stars On the 7th January they cut my services I call and ask for a yearly quote and they tell me my account is on monthly subscription I ask to change to yearly and they say it can only be done after I make a payment of R4550 I make payment on the 8th January give them a call to ask if my subscription is yearly and they say no its monthly we got a problem on our side enjoy the services while we sort it out I call on the 9th to make sure its sorted and it wasnt and they tell me it's because I owe a balance of R65 of reconnection fees and if it's not pain within 24hr the price will change I make payment exactly 19hr after the conversation and gave them another call on the 10th jan to make sure my subscription was yearly and they tell me it is yearly but u have to make a payment of R294.81 before the 2nd February when I ask why they change my subscription to monthly again do they know what they are doing? How can a company used by many be so unprofessional?
