COLLECTION OF LTE ROUTER

I NEVER HAD ANY ISSUES WITH MWEB UNTIL ONE DAY MY LTE DOWNLOAD SPEED BECAME VERY SLOW, PHONED THEM TO HEAR WHAT THE ISSUE WAS. APPARENTLY I NO LONGER HAD COVERAGE IN MY AREA AND THEY THEY COULD NOT OFFER ME A SOLUTION AT THE TIME SO WE HAD TO CANCEL THE CONTRACT IN FEBRUARY. MWEB SAID THEY WOULD ARRANGE FOR THE ROUTER TO BE COLLECTED BUT UNTIL NOW THE ROUTER HAS NOT BEEN COLLECTED AND AS A RESULT THEY STILL TRY TO DEBIT MY ACCOUNT EVERY MONTH. I HAVE PHONED MWEB PREVIOUSLY TO MAKE ARRANGEMENTS FOR THEM TO COLLECT THE ROUTER WITHOUT ANY SUCCESS.
