Poor service

I did not make a payment for December at Teljoy. However I made arrangements and promptly paid on the 23rd of January and sent proof of payment via email to *** as instructed. The January payment debit order went off on the 25th as agreed. (ref no ***). No acknowledgement from Teljoy about this payment.

Today (31/01/2020) another debit order went off (ref no ***5)00534). There is no arrangement for them to debit my account on the 31st and no payment was due to them.

Now it means I have paid them 3 times in 1 month. This is pathetic service from a company that is purportedly professional.
