Dissapointment of a Company

At this point I don't know what to say, It would be an understatement to say I'm disapointed with their service. I've been with them for more than a year now but nothing is changing they have the worst support. I changed card details and paid that R1 they charge for changing card details. Weeks later they charge the previous account. So I went out my way and asked for the link to make the payment myself. Which I did and sent my statement as proof of payment. Sent me an email sqying thanks for hounoring your subscription blah blah... The next day on the 26th I woke up to my phone locked. I had to go to their slow and unproffesional support assistants to get help, had to sens the same statement 3 times they confirmed that my device was unlocked but till today 4 days counting the device is still locked.
