BLOCKED BUT PAID FOR DEVICE

I am a woman who is currently on maternity leave and has certain payments received late. I recently made a late payment for my device using a payment link that Rentoza sent to me using their whatsapp channel, all was well until I started getting phone calls from different people saying that I need to make a payment. Long story short I advised payment had been made and they advised that they were going to message me to get the pop, a couple of days later my device got blocked and has been blocked ever since even though I made payment and when I enquire they ask me about a statement which I send but they say they still can't assist because they have not received the payment. It has been 5 days since the payment was made and they are still saying they have not received the payment.

This is the worst service I have ever received from Rentoza and honestly want to be done with them to never use them again because of this. I am a woman who is on maternity and needs to be incontact with family but I can't do that because of a locked device that I paid for.

THIS NEEDS TO BE FIXED ASAP. VERY UNHAPPY CUSTOMER.
